Pulled the Westerbeke 50 out yesterday. Everything was disconnected except for the control panel, so it was just a matter of jacking it up and building a cradle high enough to pull it out. By the way, Step 1 was to immobilize the shaft in case any movement caused the LasDrop seal to spew water...

Here are descriptions of the images:
1. Jack in place with ratchet strap to keep engine from going backward. This was soon replaced with come-along strapped to the mast.

2. Come-along pulled engine forward a bit to clear shaft hub. Engine jacked up about 2", need to go to 3" for bell housing to clear from of forward wall of the engine well.

3. With the forward part of the engine with 2 2x4s under the two forward mounts, the back is jacked up at the transmission. The plywood under the jack is 3/16" so it flexed and helped distribute the load.
When the back was up 3+", another pair of 2 x 4s were added that butt up against the first two pairs so now the engine was resting on runners 3" high.

4. At this point, it took very little effort to pull the engine straight out.

5. Almost out...

6. Now the Westerbeast is under the companionway ready to be lifted out.

7. Here is a view of the cradle. Now the real work begins preping for new engine:
Clean, paint, sound-proofing, cleaning up old wiring etc. etc...

By the way, before doing this I removed the water pump and alternator as they were two extremities that were easy to remove. Using this method, it would've been easy to raise it higher if it were necessary.

More later.

Beta recommends measuring for custom mounts with the old engine out. I'll pull the Westerbeke out Monday (when our club is closed and there is less activity at the hoists). Then I'll measure and send in dimensions. Stan sent me info and images on a T37 / Beta 38 repower and all they had to do was minor spacing. That differs from what others reported.

Anyway, once the custom mounts are settled I'll order the engine. I assume the cradle will have to be rebuilt for the Beta 38 to slide (pulled) in.

If delivery takes 6 weeks (like Stan estimated), I'll be lucky to have the back end of the boat cleaned up and painted with new materials in place by the time it arrives. I want to be ready to drop it in so it's not taking up loading dock space at our club.

Built a skid similar to yours on two occasions, once to rebuild about 17 years ago and last fall for the new Beta 35. On the replacement, we lift the old out and unhooked the hoist, hooked to the new with custom mounts and went right in. Crane time less than an hour and used same skid to slide it back in. Very controlled, we used a 2x4 to raise it up to get the oil pan over the sump. Good luck with the install.

You make a good point about use of the 2x4 to raise the engine up if the skid or cradle is flush with the mounting bed. I assume you mean like a lever to lift the engine over - true?

The images I saw on this site showed the 2x4 runners even with the mounting bed. I started out thinking that would be the way to make it, but it was clear the engine wouldn't be high enough to clear the well it sits in.

The idea then became to jack up the front 3+" and put 2x4 under the front mounts (long enough to act as runners) and then jack up the back to even it out. This was less load than trying to jack up the whole engine.

I assume with the Beta 38 I'll rebuild the cradle after considering its dimension. The posts I've seen here report being able to slide it in and out on 2x4 runners level with the mounting bed (or bearers as Beta calls them). Now I wonder if that method required nudging it up to clear the front fiberglass face of the motor well.

I'm guessing that you got the deep sump, which is std. It's better, holds more oil and helps maintain oil pressure when motorsailing with the boat healing.

Ours the skid was level and in-line to the engine stringers, but we added two 2x4s on each side to help slide back. Then they were pulled out after the engine was slide back and sitting over the stringers. I remember using a bunch of 2x4s and blocks of wood as leverage to get the pan over and the sliding 2x4s out.

Used a 4:1 boom preventer to the mast to control and help ease the engine back. It can take off in a second. Also helps hold it while you verify alignment. I move the the motor forward half inch. The reason was, that gives me the clearance needed to pull the tranny without moving the motor forward.
