Repowering. Where on the US east coast?

The Pearson 424/422 came with 58-60 HP from the factory and a couple of times I used every bit of what I had maneuvering in tight spots. Not sure if I would want to go with less but could be a new B50 has as much power as my 40 year old Westerbeke 58.



Have considered DIY. Have done all the other engine work since I bought the boat but I'm not as young as I used to be and getting pretty tired of being a mechanic. Guess it was wishful thinking but was hoping to farm out this job.

If the job requires new engine beds etc you can be into significant work.

Of course the correct prop, reduction in the gear etc is necessary but if you don't have the horse power to spin the prop, no matter what prop you have, you're going nowhere.

Takes both.

Correct. But in general, a larger, slower turning prop with more blade area will have better low speed thrust at the expense of lower top speed (due to more drag from the blades), assuming the same engine and that both props are pitched for proper engine loading at WOT. The small, fast spinning prop may perform better when the boat is moving near its top speed, but it'll produce less useful thrust when the boat isn't moving (and therefore won't be as good for close quarters maneuvering).

Nice thing about Beta Marine is they will supply custom mounting brackets for their engines so most of the time will be a straight drop in to the existing engine beds.

Here's hoping that will work for me.

Skip,
I responded to your PM.

I put a Beta 43 in my 44' Ketch to replace the Perkins 4-108. Had the yard do the heavy lifting, the rest DIY, not hard just tedious. Works great.

I'll recommend Yacht Maintenance in Cambridge MD, you can order the engine from Beta Marine NC and have it shipped to YM. YM allows you to do your own work or you can have them do the whole thing. Beta's are available with custom engine mounts which might be less costly than having the yard modify the bed.
Good luck.

You may want to do a hybrid of DIY and hire a strong back to help you. There are lots of "boat mechanics" that, with proper direction could help you remove the engine. Then you could do the engine room clean-up and paint. On your boat, having the fuel tank behind the engine like mine, I would inspect that thoroughly, if not replace it. You could do that yourself and also any mods to the engine beds.

Yes all completely correct. However, since I have carefully checked the prop pitch and diameter, compared to the props on sisterships, verified rpm at max throttle on my actual boat, etc I am pretty certain I already have the correct prop for my boat and don't have to address this aspect of engine HP at this point.

And the engines I'm considering have similar torque curves and rpm limits as the existing engine so don't see any concerns there relating to the existing prop.

If you go with a Yanmar, either OldPort Marine in Newport or Bay Shore in Annapolis (at Jabins)

I put the Beta 50 in a Beneteau First 456. Cruising displacement was about 33,000 pounds. The beta is rated at 2800 rpm vs 3000 for the Westerbeke, and looks like it has a bit more torque at lower rpm. I had the option of raising the engine beds with 1.5 inches of whie oak or getting custom mounts, and chose to raise the beds because the standard mounts are at the center of mass, reducing potential vibration. I repitched my maxprop at the next haulout to accommodate the change in power, RPM, and transmission ratio from the old 4108.

I did the swap on a mooring at Prudence Island in Narragansett Bay, but I would trust Bock Marine in Beaufort NC to do the work for me. Good folks, and labor rates are much lower than in the NE.

I repowered MOJO at Tiffany Yachts, Burgess, VA., off the Chesapeake Bay up the river from Reedville. Excellent work ethic and skill level by all personnel. This is a family owned and operated boat yard. Talk to Randy or his son Taylor Cockrell. (804) 453-3464. Don't let the name Tiffany scare you off, the yard was founded by Tiffany Cockrell and his father Otis in 1934. https://www.tiffanyyachtsinc.com/our-rich-history/

I am having mine done now at Zimmerman, (formarly Deaton Yacths in Oreintal).
I have an 30 Beneteau 361 and they are installing a Beta 30. Beta took a long time to get my engine but I know several others with a larger model who had no trouble at all. I bought mine on sale in January for $13,600 with some extras and had it deleivered to David at Zimmerman. It came the last week of May. His Diesel guy is Gary and seems to know his way around a repower.
They have been very straight with me and have talked me out of doing some work I thought I needed.
I have no idea what the exact labor total will be but they seam to be trying to hold the cost down. They gave me some ranges when I first discussed the job and I expect the cost will be somewhere around $8,000 fto $10,000 for their work and minor parts.
If your interested, pm me and Iwill tell you what they end up charging me.

So right now, my advice would be to order my engine and have it deliered to Zimmerman there in Oriental, and get in thier que to get the work done. Supply chain what it is, you should get your engine order in.

Also, Beta USA is about 15 miles from their yard.

Hartge Yacht Yard in Galesville MD may not be able to install a Beta, but generally the work they do is of the highest quality.

[pitlaw]

I have been customer of Hartge . They can do any heavy duty engine work Call and ask for Alex Schlegel the owner and ask away. Solid reputation

I have re-powered twice in 40+ years with my Tanzer 28. The last time with a Beta 25 in 2016. I am pleased with its performance and since then took the boat to the Bahamas from the Annapolis area. It was basically a DIY project at Ferry Point Marina on Mill Creek off the Magothy. I had their Head Mechanic, Mark Miller do the engine alignment. I am also getting long in the tooth so I get Mark to handle critical or difficult task. DIY does save a bundle of money on an engine change and it does give one a chance to clean up the engine room and upgrade other systems when the engine is out.
