Amazing A-4 economy for sure…The ‘burn’ with our old A-4 in our 32-II averaged 1 gph. Our replacement Westerbeke 20B averages 1/2 gph.Wait, you're getting 1/2 gallon burn on gasoline? That's diesel rate on an M25.
Thank you for this! Very useful and I appreciate the information!Not to steal his thunder, but @p.gazibara documented it here: https://www.sailingcinderella.com/
If you want something that's more of a kit, Thunderstruck Motors sells several different sailboat kits along with the necessary gear reductions. This guy did a Thunderstruck conversion on a Catalina 27 and documented it on his channel.
Thank you very much indeed!Hi Kaitie and Fanfan,
I posted a few blogs on this site about the electric propulsion system I installed on Lotus Flower a while ago. I'm not sure how you search Blogs but I think this will get you there. I do need to do an update....
Well, three and half years into life with electric propulsion (EP) on Lotus Flower a 1976 E27 I think it's time to log some thoughts on the web. I will start with a timeline of the process.ericsonyachts.org
Loren, did you get the Beta 25 that's got the mounts same as the Atomic? Also, I'm curious how much taller it is, and if your engine is mounted in the cabin like my 1972 E35-2 is?? Sorry I have a million questions.The advice to rebuild the existing A4, is looking practical. Considering IF the original poster could get the same deal I got in 2018, for a new Beta25 installed for about 15K total, it's probably still way more than he may want to budget. I like diesels for all of the usual reasons, but individual circumstances are most important.
Best to ask the A4 guy @ Moyermarine with the good reputation what a rebuilt engine would cost. Also, you know it should/will fit without mods.
I did not buy the B-25 with the A-4 mounts, because I was replacing a Universal M25XP. Height appears to be about the same, maybe a bit less; actually the whole 'footprint' is a bit smaller and lighter weight than our former engine. You can d/l the Betamarine dimensions from their web site. Take careful measurements, and measure every which way -- twice!Loren, did you get the Beta 25 that's got the mounts same as the Atomic? Also, I'm curious how much taller it is, and if your engine is mounted in the cabin like my 1972 E35-2 is?? Sorry I have a million questions.
Like does your boat have a 3/4 shaft?
Did your Kubota (Beta) 25 come with a warranty?
Have you written about your repower experience?
It's an odd similarity, but my iphone 7 just died, and I could keep it going for maybe a year with a fair bit of effort, and then it would die permanently, or get a new phone. I chose to get a new phone. It works, and will work for hopefully some years (the 7 lasted 6 years)
Now my engine has died, and I could spend 500 to maybe fix it, for ? knows how long it will run. Ken from Moyer says it's had a lot of hands on it doing awful work to it, and so I'm faced with a similar decision. Fix it which may work for ? how long, or go for a diesel beta 25, preferably new, which if well maintained (which I would) could last a long time.
I have had the opportunity to work on Westerbeke, Perkins, and several of the various marinized tractor engines, and that has made me respectful of Yanmar. Yanmar's engineering for marine use is not an afterthought like the others--they invest in the metals that resist degradation and corrosion that probably cost a bit more than black iron pipe and mild steel elbows we see on most tractor engines. Yanmar cooling systems are integrated into the engine design. My 25XP runs fine for what it is, but requires a lot more intervention to keep it that way because the dissimilar metals in the cobbled cooling system and the whole thing is tied to a transmission that is questionably adequate for its application (an HBW 50--for which parts are no longer available). My Yanmar has never needed a glow plug to start instantly in any weather--which testifies to the precision and tightness of the mechanical parts. Yanmar's customer service for small marine diesels stinks and folks like Beta Marine have managed to do a much better job of working with customers both in advertising, sales and service. I installed a Yanmar in my Tartan 37 ten years and 1200 hours ago, and would go that route again. I would likely go to Yanmar if my 25XP ever gives up the ghost. But I do not expect that, as most of these small diesels will run longer than my life expectation if I keep it in clean fuel, lubrication, and babysit the cobbled cooling system. I appreciate that maintaining it keeps me from straying into drug use in my spare time.The BEST upgrade on my 1971 E29 was a new Yanmar.
It is keeps on working well.
And therein lies the potential problem. Both an expert shipwright and the Betamarine dealer for this area are friends and members of our little YC in Portland. I was able to do the engine changeout at our slip, with help in many key parts.Well I'm ready to repower. Haven't decided to what. Probably electric.
But I am having trouble finding a marine service or yard that is enthusiastic about doing it.
Anyone know someone within, say 20 miles, of Annapolis ? (or mobile)
