Main Message Board / Core Repair Under Cowl Vents
« on: July 11, 2019, 01:08:14 PM »
So first, let me set the scene...  My cowls were not mounted in a dorade box or even using a plastic cylindrical dorade.  This is a problem, but not the basis of my question.

I plan to replace the cowls with marinco day/night solar vents, but prior to making that decision, I thought I might just try to rebed the old ones and deal with the lack of dorade.  What I had on the deck was a teak ring, maybe 1.5" tall and the deck plate into which the cowl threaded was mounted in that ring.  4 screws went through that plate and ring and into deck to hold it in place.  The bedding apparently long since gave up the ghost, and the teak ring had split along the grain, both allowing water to penetrate into the deck and rotting out the core surrounding them.  My first indication of a problem was dripping from the teak ring mounted inside the boat supporting the screen.

When I removed the inner ring, I could see a split in the fiberglass tube where the deck had swollen when wet maybe just swelling with the water, maybe with freezing of that water, not sure.

I removed the cowls, deck plates and rings, covered with plastic and duct tape, and sprayed the heck out of the surrounding area (traveler bar included) to see if the cowl deck plate screws were the source of the water or just where it ended up.  The area stayed dry, so I'm going with my theory that the four screws were the source of the water.

I have new deck plates and screws but first have repair at least some of the bad core... which is actually what I have questions about.

I'm trying to determine how much glass, if any, to cut out, or whether to just overdrill, fill with epoxy, and redrill for through bolts when I replace.

Thoughts, recommendations, horror stories and constructive criticism all welcome. :)

First let me say that I religiously store my key on my strainer thru-hull.  I never take that key off without first opening it, and that's just what I did this weekend... but then I decided to clean the strainer out and I closed it again.  When I was ready to go, I fired it up, untied my lines, ignored my wife when she said something didn't sound quite right, and left the dock.  I got to the end of the dock, got the alarm, realized I was overheating but not the cause, spun around, put it back in the slip and shut it down.  That's about the moment I realized what I'd done so I opened it, fired it back up and watch the temp drop nicely.  After giving it a chance to cool and verify that operating temp was normal, I set out for my weekend with friends.

Now that I'm back in my slip again, I'm wondering what I might have damaged and what maintenance, preventative or otherwise, I should do to tell my poor engine I'm sorry.

I plan to change my oil and, because I'd already purchased a new raw water pump (OD to replace the sherwood) I plan to replace that rather than just the impeller that I may have damaged.

Any other recommendations?

Main Message Board / Engine/ control panel mismatch

I have an M35AC engine but a M35BC engine control.   Normal?  Unusual?   Worrisome?

Main Message Board / Compass light wiring
« on: May 11, 2019, 08:46:34 PM »
I've just rebuilt much of my pedestal and had my compass refurbed by Ritchie.  All is good now except my compass light.   I don't have any voltage at the pedestal.

I have a gray sheathed black and white twisted pair that drops out of the pedestal base.   From there it heads in the general direction of the stern light and engine control panel.  The pair doesn't come out behind my electrical panel or my engine panel.

Can anyone tell me which switch should control the compass light?  Nav/comm? Running lights?

Anyone know where that wire pair should run?

Main Message Board / Tubing/Connector Size from After Water Tank
« on: May 06, 2019, 09:19:39 AM »
My after water tank is easy to remove EXCEPT for the outlet connection under the tank, which has me making up new ways to curse every time I have to do it.  I'm thinking about ordering quick disconnect fitting(s) for that line.  Does anyone recall the tubing size and the thread size/type for the fitting at the tank?

Main Message Board / M35A Block Coolant Drain
« on: April 01, 2019, 08:48:56 AM »
It seems I have a leak around the block coolant drain on my M35A.

Whenever I return to my boat, I'm finding a puddle of coolant under it.  Not enough to show up missing in the reservoir but enough to puddle in the forward edge of the sump under the engine.  I can see evidence of dripping off the bottom rear corners of the oil pan.  The port side of the pan seems dry but on the starboard side, I found this.

The rusty area is damp to the touch.  I see corrosion on the smaller/inner plug but felt no moisture there so I tend to think the smaller plug had a leak, was tightened, and no longer does, but that the outer plug threads have leaked for a long time.

The leak has been masked by a diesel fuel leak that I just addressed by replacing the fuel pump.  Fingers crossed this is my last (current) leak.

I don't want to remove the plug until I have a replacement or at least a plan.  The kubota dealer tells me that they can't get one... the one their book shows has a hose barb apparently.  Anyone know a source?

Has anyone ever had theirs out and know if that's pipe thread or if it's straight thread and has, or should have, a crush washer or gasket?

Main Message Board / Plug size for holding tank macerator outlet
« on: March 27, 2019, 12:51:57 PM »
Hey gang... macerator only works if the goal is to flip a breaker, but since I'm inside 3 miles when I do my sailing it doesn't much matter.  I'd like to pull it, though, to be replaced if and when we get to get to take an extended trip and make the jump to the Bahamas.  Meanwhile, I'd either like to either plug the outlet, or add a valve at that outlet that would allow me to replace the pump while the tank is full.  Anyone know the thread size/pitch for that outlet?  I'd prefer to go to the boat with one in hand.

Main Message Board / Raymarine Evolution EV-100 autopilot settings
« on: February 04, 2019, 03:46:55 PM »
Can anyone running this autopilot that's happy with the performance tell me:

1) what you are using for vessel hull type (sail or sail (slow turn)?)
2) Wether you have a rudder position sensor?
3) If you don't have a sensor, what you used for rudder limit setting (did you leave it at 30 degrees?)
4) What you used for hardover time?

Main Message Board / Ronco Holding Tank Model Number Anyone?
« on: January 09, 2019, 04:00:12 PM »
Can anyone tell me the model number for the Ronco holding tank that would have been original equipment in a 1992 M1.5?  Even better, tell me where to find that marking on the tank?

With any luck it's obvious, but I'm going down this weekend and one of my chores is to determine if my tank is OE.  I'd like to get the dimensions from Ronco to use for that purpose.

Main Message Board / Peggie Hall
« on: January 04, 2019, 06:32:44 AM »
Does anyone have a method of contacting Peggie Hall other than a private message on this forum?  I wasn't successful that way and I'd love to buy an hour of her time to help me solve a problem.

If you have an email but don't feel like you can share it, my email is rmbrown@code-refinery.com... maybe you could share it with her?

Main Message Board / Alternator/Raw Water Pump Impeller Screw Head
« on: December 28, 2018, 04:29:43 PM »
Since I installed a higher output alternator and external voltage regulator,  and I'm tweaking the belt manager setting,  I cleaned up and looked for belt dust.   I found some but quickly realized that it was due to the edge of the belt touching the head of one of the three cap screws holding the impeller cover in place.

I found a relatively thick lock washer under all three.  The parts diagram for the M35AC shows the thinner star type in use.   If I remove the existing lock washer,  I have clearance but I'm wondering if mine is the only one this close?

Main Message Board / Voltage Regulator Mounting Location
« on: November 23, 2018, 04:31:07 PM »
I swear, I remember a discussion on this topic, but my searching skills are lacking today.

I'm headed to the boat tomorrow to mount the new external voltage regulator and I'll wondering what the best spot is?

Suggestions?

Main Message Board / V-Berth Cushion Insert
« on: July 27, 2018, 03:19:59 PM »
Does anyone have a picture of the v-berth cushion insert in place in the lower position, as a seat?  I'm going to cut a shelf to fit there and I'm wondering if I can make it out of something 13" deep rather than 14" (because I have a piece of mahogany that would look nice) but I want to be sure that it will be adequately supported.

Main Message Board / PT11 / PT-11 / PT Eleven Nesting Dinghy
« on: July 27, 2018, 03:13:08 PM »
Anyone have any experience with this dinghy?  I'm liking the kit and all I've read and seen, but will it fit on our foredeck?  And has anyone actually rowed one?

Main Message Board / Lewmar Winch Spindle Tooth Deformation
« on: May 20, 2018, 10:36:45 AM »
Hey gang:

Pictures to follow but, while rebuilding my two Lewmar 46STs and my two Lewmar 30STs, I found that the teeth of the center spindle are deformed to the point that you can't get the spindle out of the top of the winch.  I removed the winches to rebuild in my shop anyway (from the look of things, the hardened grease might be original equipment) and all else seems to be in order.  I had no indication of any trouble, just doing preventative maintenance, so I don't know that this an issue that has to be fixed.

I'm planning to, at a minimum, grind or file to reduce the diameter to original specs so I can get it out from the top on future rebuilds, but I'm wondering a couple of things:
1) What in the world caused this deformation?  It's hard to believe that someone cranked that hard.  I've wondered if someone left the winches loaded over time, which is possible I guess, but still shocked it would cause this.  The winches are just for halyard use and haven't been left loaded since I've had the boat (about 1.5 years).
2) Am I better off trying to reshape the teeth or leaving them as is?

Pictures to follow.
