New Project Boat

[Bill kubiak]

Just got a 1980 Penn Yan tunnel drive V-8 inboard with a frozen engine. Prior owner could not start it and removed the plugs and then let it sit for about a year. I have filled all the cylinders with mystery oil and hoping that will free it up after soaking a few days,
Under the motor is a deal with a clear top and hoses running to it that looks sorts like a spaggetti collander. This is my first inboard and I have lots of questions. What is that thing? It looks like some sort of strainer.

Re: New Project Boat

Your "spaggetti collander" is probably the raw water strainer going to the inlet side of the raw water pump mounted on your engine.

If your engine was frozen up before it sat for a year, I normally call those junk. No spark plugs, humidity, open spark plug holes equals rusted cylinder, water in the cylinders, probably frozen rings in the grooves etc.
The engine needs to be pulled and gone through to even make it close to dependable to take out on the water. Unlike a car, you can't just walk home when it finally dies on you.

Re: New Project Boat

Howdy,


Frozen marine engines are frequently junk.....or after you get it running it shortly becomes junk. Good luck on that.....


The spaghetti colander?

Post a picture!



Cheers,

Re: New Project Boat

If it sat in his garage protected it might be ok? Not in the elements though. I have gotten lucky with a few old engines doing the same thing.

Re: New Project Boat

actually i poured a half a quart of transmission fluid down (and let it settle) the carb of the last dust collector i tried to start. It was 10 years old when i started it from sitting for 3 years. (did replace the fuel pump first) Then drove it for 100,000 miles.

Re: New Project Boat

Well, if it was inside all the time you might luck out......But engines that sit inside don't usually "freeze-up" either.

post some pictures of the boat!.....We all like pictures....

Ayuh,... That's the Sea Strainer,...
I agree with Don,... The Odds are about 1,000 to 1, that motors Junk...

Re: New Project Boat

Adding to all the above is the fact that you are in Miami. The high concentration of salt water in our area adds to the potential of the engine being "toast." If you do try to get it to turn over, do so by hand - not with the starter. Otherwise you might be adding other items to your "need to replace" list if and when you do pull the engine and evaluate. Good luck with it!

Re: New Project Boat

Just got off the phone with the prior owner, he said he pulled the plugs 4 or 5 months ago and he said it turned over fine then with the starter.

How can I tell what brand engine and horsepower it has? The exhaust riser says PCM Marine Engines.

The rudder is kinda funky it has a zig zag to it, what's up with that it looks diff then other rudders I have seen

Dude,... Ya gotta provide a few Hints,....
We can't see it......

Pictures would be nice....

Re: New Project Boat

i found a tag on the engine that says Pleasurecraft Marine Engine but it does not give the cid or hp. What other engines are comparable to that tranny?

When the shift is in neutral I can spin the prop by hand

Put a 7/8 socket on the bottom pulley and I managed to loosen the nut.

Also the port pipe on top of the exhaust manifold has what appears to be a long crack in it

How do I post pictures it wants a url number??????

Re: New Project Boat

The distributer is in front, C'mon guys I'm not about to buy an engine unless I have to and I would probably part the whole boat out first.

I want to see if I can get it free and running and go from there

I haven't read where anyone has simply said to go out and buy a new engine.

Some have given their opinion, (based on the little info you gave), that the engine is probably no good. But most have said that the best way to proceed is to pull the engine and go over it and see what the story is.

With the additional information you have given, it may turn out that you will be able to salvage the engine.

Maybe you can. Best thing to do is to try.

Read the posts about how to post pics... that helps.

Also - instead of using a big socket on the balancer bolt - make sure the belt is tight and try turning the water pump pulley by sticking a strong bar between the bolt heads.

Re: New Project Boat

Here is what I found on the pleasurecraft engine group website based on the model number on the engine #PRD00000
Pleasurecarft Engine r/h rotation
351 cid ford 240 hp
It was shipped without a tranny, so I do not know what tranny is in it.

As far as pulling an engine to work on it, I am 71 years old and the boat is on a trailer in my side yard and that will be an absolute last resort.
PS. I paid 500 bucks for this boat on an almost new, dual axle, Float On, Aluminum trailer. It has all the options penn yan offered, bimini, swim platform, bennet trim tabs, marine vhf radio, 2 each hummingbird fish and depth finders, nice captains chairs, a working anchor windlass and a bow rail. it's got some issues but I am trying to sort them one at a time, I even have a spare brass prop with it....

I just want to test my skills and try to get er going while spending the least ammount of my ss.

Re: New Project Boat

Well, you obviously got a great deal - if only for the trailer!

We don't know your mechanical abilities, but you do. Good luck with it!

Re: New Project Boat

Thanks, what is with that zig zag rudder, I saw another similar older penn yan and it had a conventionaly shaped rudder?

Re: New Project Boat

I'm going to be a bit harsh, but your engine is stuck, just because you are 71 and don't want to or can't pull the engine doesn't suddenly make it possible to salvage a junk engine.
It could have been cause by faulty exhaust manifold/risers, who knows. But dumping oil, or anything else in the cylinders of a stuck engine is just a waste of time. Yeah, you might even get it started if you are lucky. But to have it last for more than an hour is what you are wanting, and that isn't going to happen if there was salt water in there for even 24 hours.

You may like the boat, but you have to learn to face the facts. Boating is expensive, and it doesn't care how old you are, or how much you make, if it's broken, it's broken.

It is???

Re: New Project Boat

Wow you guys are harsh. I thought you were here to help, not discourage. No salt water was in engine. The prior owner had a running boat that he flushed with fresh water all the time. One day it turned over but would not start, so he pulled the plugs to do a tune, something came up, he dropped the hood and threw a cover on the boat. Then he lost his job. It sat for maybe 4 months, then I got it and it would not turn over at all. Same with the steering cable, iut was stuck, cleared up the cable and got slick steering. I have not put any pressure on anything trying to turn it over, yet....
I have saved many a motor in my day, mostly outboards and a couple of motors in old cars that sat in fields for years and years. This is my first straight inboard, I figure if it ran four months ago and now it is stuck, it can not be all that bad.
