Main Message Board / Transmission to prop shaft coupler bolts loose
« on: March 31, 2021, 07:42:58 PM »
While trying to figure out where the coolant leak might be coming from, I noticed some of the bolts on the transmission to prop shaft coupler are loose and spin easily.  I think one of the nuts was actually able to be spun off.

I don't think this is normal!

What is the correct tightness or torque, and shouldn't these nuts be Loctite'd (i.e. low strength purple 222 so they can be removed if needed) to prevent this situation?

In the photo you can see the gap where the arrow points.

Thoughts?

Main Message Board / Electrical Connections under Pedestal
« on: March 29, 2021, 01:57:39 PM »
I noticed a leak in the aft berth that has required the recovering of the aft berth mattresses.

It looks like the seal around the pedestal to cockpit floor that allows the wiring to the instruments to pass thru is leaking.

Is there another area to rebed other than this connection?

Also can someone recommend an approach to clean the connectors?  They rusted due to the (fresh) water, however all the instruments and VHF are working.

Last season I had no speed and therefor no true wind either.  We sail on a river with steady current, so it is useful to see what the current is relative to SOG.

-Boat is in fresh water
-Paddle wheel spins freely making a fun 'zing'! sound, paddle wheel shaft looks good
-Able to get speed to indicate on instrument with someone spinning the paddle wheel
-Pulled speed transducer and found a split O ring at the base closest to the paddle wheel
-Transducer showed signs of dampness on body as shown in photo

From other reading I've done on this topic the transducer may not be a sealed unit and the failed O ring allows fresh water to get into the transducer and short it out when the boat is in the water.

Assuming this is correct, what is the best approach to correct this?

I'm assuming I should dry out the transducer, possibly spray it with some kind of hydrophobic solution to clear out the water trapped in it (WD 40?) and replace the O ring, re lube the O ring seals (3 of them on the transducer) and reinstall.

Is it possible to get a new O ring or am I stuck with having to purchase a whole new transducer..?

Considering how questionable the design of this unit is with 1 O ring between the outside and the internals of the transducer I'm hoping there are readily available parts!

Main Message Board / Engine loosing coolant
« on: March 17, 2021, 01:48:46 PM »

Boat is on the hard from last season.  I live in Ottawa Canada so we haul out every winter.

-Port lazarette has signs of coolant leakage from the coolant recovery tank.  Can be kept tidy with a shop cloth changed every few days.
-Engine had low coolant at beginning of year last year
-Current level of coolant in engine is low
-Coolant is in the bilge

Can anyone point me in the right direction as to where to start looking for leaks? Last season I kept topping up the recovery bottle, and checking coolant level in the engine before every sail.  I'd like to get this solved. 

Hopefully the pictures can help.  I haven't done my spring cleaning yet so the boats a bit manky!

Main Message Board / Grease for feathering prop
« on: March 14, 2021, 09:47:02 PM »
I searched the forum, and I found 2 references to Variprop and neither were what I needed so I thought I'd post!

I have a Variprop, and I need to grease it.  The below is from the manual, but ABMarine sells this stuff for a $60 USD plus shipping.  I find it hard to believe that it's that special.  Canadian Tire sells 'Marine Grease' that states it is for wheel bearings, trim systems, etc at nowhere near that price.  https://www.canadiantire.ca/en/automotive/oils-fluids-additives-chemicals/grease-gear-oils-lubricants/marine-grease.html

Can anyone tell me if the ABMarine product is the same as the CT stuff, or point me to similar?

"The propeller body must always be completely filled with a high viscosity grease. We recommend
 synthetic grease typ TW.2 GEL or mineral multi-purpose grease EP/SAL 8 (see servicing page 10 )"

Main Message Board / Shore power electrical shock
« on: August 31, 2020, 08:59:55 PM »
Plugged into shore power I got a good shock when my hand connected the midship cleat and the holding tank stantion.

I used a voltmeter to investigate and I measured 130V AC. 

This only happens when the breaker on shore power is On. Panel is still set to off for AC.

Any thoughts? The wiring is factory no mods to AC.

Main Message Board / Anchor fit
« on: July 21, 2020, 07:20:08 PM »
New to me MKII.  Anchor will not retract onto roller without shackle getting stuck and I have to reach through the pulpit to fiddle around and get it through.  This is not easy to do at the best of times, and very difficult for smaller crew!

The issue is pretty clear, however I could use some recommendations on how to make the anchor and rode I do have work.  I'm not well versed on what makes up a good anchoring system.

I'm also open to suggestions on a new anchor etc, however I'm hoping there is a way to reuse the existing setup.

It's around a 1 1/2 inch chain, and 3/4 inch rode.

Thoughts?

Main Message Board / Delaminated Seahood / companionway cover
« on: June 11, 2020, 04:56:02 PM »
On my 2001 34 MKII, the U shaped coachroof piece that wraps around the companionway hatch has split underneath on the port side 'U' that covers the rail. 

The gelcoat has delaminated and split with moisture in it.  I'm assuming one of the screws has leaked over time.

Is there a fix or a way to replace the coachroof piece? 

I don't know where to find a parts catalog...
