Pearson 31 engine

The P31-II came with a Yanmar 2G diesel. This is an excellent engine. Go to any marina and half the 30 ft class boats will have this engine. The P-31 is well laid out and the engine is very accessible. Installing a new engine should be a fairly straight forward operation given that the engine mounts and prop shaft are in good shape. Go for the inboard. This is too much boat and way too heavy for an outboard. I'd guess that it would be very difficult to handle with an outboard. That is a bad idea.

Open the filler and sniff. See if you can smell whether it has or had gasoline or diesel in it.

Do research on-line (Google is your friend). For the year of your boat. See if you can find out whether they typically had gasoline or diesel engines in them.

There used to be a very active Pearson mailing list hosted by Sailnet that was a terrific Pearson resource, but I guess they weren't making enough advert revenues off the mailing lists they hosted and they one day just up and pulled the plug w/o warning. Now there are two Pearson mailing lists, one on Yahoo! and one on Google, both of them together not having as much traffic as the Sailnet one used to have, I'm told. But you can look for them, join them, and ask there. The Pearson activity on Sailnet's web forums, which is where I imagine Sailnet hoped to drive everybody, isn't even merely a shadow of the old Pearson mailing list activity.

Here's the thing about "cheap" boats: They more-often-than-not aren't. Rarely does somebody just up and "give away" a good boat that's in good repair.

You should probably pop for having a qualified sailing yacht surveyor give her a good going-over before you're out one day in a stiff blow and find yourself with your mast, rigging, etc. down around your ears, or worse.

Good luck.

outdoorsman37 Thanks everyone! It has a fuel tank but I don't know how that helps. I will take a picture this weekend. Yes I did get the boat cheap. The engines that I have read will work follow:

Westerbeke 30;
Universal 3 cylinder;
Yanmar 2GMF,
Perkins 4-107

I can get a Westerbeke 4-91 30 cheap. Should I do it? everything points me to the yanmar 30 or 20.

any comments? any other engines that would work?

DropTop I agree with the above posts, an outboard is not practical for a boat that size...

I have an outboard with electric start and remote shift / throttle in the cockpit on my 5,000# Hunter 27', and I'm glad I do most of the time (low maintenance mostly), but I also know that if my boat was any bigger or heavier it wouldn't make sense to have anything but an inboard.

I would never recommend a outboard on anything larger than a 28', and hardly ever recommend an inboard on anything smaller than a 27'

tomandchris Agree with SF...$10-12,000 is conservative unless you are doing everything yourself.

Actually from my experience it'd be a conservative figure...have you paid to install a new inboard?

Sailmachine $10-12 seams high to me.

sailingfool Attempting to put an outboard on a boat that size is an unworkable idea. IF you are able to hang one off the stern, you won't be able to reach it to operate it. IF you can reach it, it will provide lousy service. The P31 is a nice boat, unless you want to reduce its value to zero, you need to install a working inboard. In terms of new engine, a Yanmar is the way to go.

Hopefully, you figured the new engine cost of $10-12,000 grand into the price you paid.

Sailmachine I had an outboard on a sailboat before but never again. When you get into rough weather it wont stay in the water. Makes it hard to control the boat. Go ahead and try it, if you're like me you will only do that once.

tomandchris Outdoorsman,

I am hoping for the best for you, but if you are asking this question after the purchase I hope that you are aware that this is a very expensive decision. An outboard on a boat that size is not going to be very effective. That leaves you with a A4 or a diesel. Both can be expensive. First you have to figure out what was in the boat. If the fuel tank is still in the boat it will probably give you a clue.
