Yes, I'm sure it will.  Great wealth of knowledge on this forum.   It was a small amount of sanding I did with very fine sandpaper.  Amazing how the pump went from no flow to full flow with just that little amount of sanding.

I had the same issue with my lab.  She was 6 by the time we got our first boat.  Just couldn't get comfortable on it, and we never even sailed with her.  Just the rocking, of the boat, at the dock was too much for her.  Couple people at my marina have dogs.  Ones a Yorkie.  Others look to be mutts.   I think the key is getting them on the boat when they are puppies.

Went down this morning and tried Stu's technique with the sandpaper.  It worked! Put everything back together, turned the engine on and water started coming out of the exhaust.  Let it run for a while, temp got up to 160* and held.   Thanks for all the help everyone, appreciate it.

Took the strainer apart and checked it out. Then reconnected the strainer to the seacock  hose and opened the seasick. Water came out the barbed fitting where the hose to the water pump connects.

Strainer to water hose. Disconnected and blew through it with my mouth. Water sprayed out the other end.

So even a slight gap between the faceplate and impeller will cause the water to not flow?  I would think the impeller would have enough oomph to overcome that.

When I run the engine for a few minutes, then pull the faceplate off, the pump housing and hoses are dry like it hasnít pulled any water at all through. I would think if the faceplate gap was the issue it would pull something just maybe not enough.

I'll take another look tomorrow.  The inside face seems smooth looking at it today but I'll check again.  The odd thing is I replaced the impeller last July, it ran fine July-Sept, or it appeared to be running fine.  Just noticed the issue getting ready for winter.  Maybe I'll try another impeller tomorrow and see if that makes a difference.

Does the engine water intake need to be primed?  When adding antifreeze last fall the engine didnít want to suck in the antifreeze I was pouring in the top of the intake strainer. Posted about it here and someone mentioned the impeller might have broken.
At the boat today. Looked at the impeller, intact. Pulled the intake strainer. Clear. Hose from thru hull to strainer is clean.  Hose from strainer to water pump is clear. Hose from water pump to heat x clear.  Put everything back together. Tutned engibe on. No water coming out of the back of the boat. Pulled water pump apart. Had my daughter start the engine water pump is Turning so that is working. 
Seems like water isnít getting pulled into engine.
Took the hose from the water pump to the heat x off, at the heat x and  turned engine on. Wanted to see if I was getting water up to that point. Figured m aybe issue was after that point. No water came out after running for a minute or two.

Please post pictures as you go along.  I'd be interested in your installation.

I have a used main sail cover from my MK-I.  About 4-5 years old.  In good condition.  It's blue.  About 1 shade lighter than the dark Sunbrella Navy blue.

Main Message Board / Re: Mast Up or Down when stored on the hard?
« on: October 15, 2020, 06:42:49 AM »
When I used to store my boat on the hard, I always left the mast up.  Never had any problems in the 4-5 years I did it.
 
Marina I'm in now lets us keep the boats in year round.  I'm in New England.  Never any issues keeping it in the water during the winter either.

Found the fins when I overheated in July. Couple in the housing and 1-2 at the heat x intake.  Since then the engine has been running like a champ, 160* all the time.  Was just when I was winterizing I noticed the problem again.  Will go down next weekend and check the impeller.

I'll check the impeller.  After the overheating in July, replaced the impeller, old one had lost some fins in the overheating.  Engine had been running fine for the last 2 months so figured the new impeller was still okay.

Was putting the boat away for the winter this weekend.  Raw water seacock was shut.  Pulled the raw water strainer out, started the engine.  Typically I run right back and start pouring a gallon of antifreeze in.  Usually takes only a minute or 2 then I shut off the engine.   This time I run back to the strainer and the water hasn't gone down.  Wait a minute and it starts to slowly go down.  Add a bit of antifreeze and wait.  Nothing happening so increase the rpm to 1800 or so.  Go back to the strainer.  It would slowly go down, stop then rapidly drop, I'd fill it back up and wait.  Kept doing this over and over.  I think it was about 15 min before it took the whole gallon.  Temp was about 185ish when I turned it off.

Earlier in the season I overheated the engine.  Since then it has been running fine, staying about 160-170 when underway.  Not sure what was going on with it yesterday.

Inlet hose into the muffler. Itís a black rigid hose. Definitely not the blue hump hose.

Like I had mentioned, I had unscrewed the clamp on the inlet hose where it attached to the muffler. I was trying to get it off the muffler stub to see if the overheating had cracked or deformed the fiberglass stub. It was sitting about an inch up on the stub. As I lifted the hose up to try to get it off the stub, the riser moved up about an inch which I wasnít sure it should be doing.

Iím going to do what Noah said and look over everything. Do I have to be in gear or can I leave the boat in neutral.

Itís clear water. A little dirty but clean. No anti freeze in it.  When I noticed the hose to the muffler was leaking and I loosened the clamp. I was able to raise up the hose and The exhaust pipe it was attached to would hinge up an inch or so. Didnít think anything of it but looking at Stuís exhaust replacement article Iím wondering if that exhaust section is supposed to be rigid with no movement.

Might have spoken too soon.  Went out for a sail Sunday. Motored about 20 min. Temp steady at 160. On thr return trip, also 20 min motor.  Was running at 160 then creeped up to 180.  When got close to the marina throttled down and temp dropped to 160.
I did notice thr was a bit of water in the bilge so something is still leaking. Will have to explore more next weekend.
