Engine - refurbish or replace ?

Thanks Rob, for a common sense viewpoint!
And use a strong light and a small mirror on a stalk if needed, but check that starboard side rear mount -- that one was down to metal-on-metal when I decided to replace all of ours. It's very hard to see.

Idle thought: I have #8 and Jay has #9, I wonder who is sailing #10? Same crew probably built out all of these.

- I don’t have a gauge but alternator belt tension appears to be good ( not too tight ) . I could believe that an over tensioned belt would cause the mount on engine to break .
You don't need a gauge. Here's a trick that works well: Find the longest exposed length of belt between the pullies. You should be able to twist it exactly 1/4 turn. If you can twist it more, it's too lose; less, it's too tight.

I'll throw this in...love this channel. This young woman did a repower (A Beta Marine engine) on her boat mostly doing the work herself in remote area.. it's over a few videos here is one of them.

I feel like I should add another option to the OP’s list.

You can always go electric. I did it on Cinderella for $1600, including a cheap set of batteries. That was 5 years and probably 15,000nm ago.

I did have to buy a quality set of batteries in 2018 for $1200. It was my fault, I left the old ones without any charging source when we flew back to the USA and left the boat in Tahiti for 4 months. We came back to dead batteries. Even then, we were able to revive them enough to go sailing around French Polynesia until the new ones arrived

Beside those batteries, the only maintenance I have done on the drive system over the past 5 years was changing one $15 drive belt.

Sounds like you current engine has plenty of life left in it, so carrying on most likely the best option. Nice to have time on your side, especially when batteries just keep getting cheaper.... opposite of diesel

Based on what you say about the engine operation and looking at the photos please take Alan's advice. Don't worry, be happy!

My old P-60 gas engine looked much worse than that for years. What finally got it was a stuck valve that was impossible to deal with in the boat and I decided since the P-60 was getting hard to source parts for I swapped in a diesel when it died.

Diesel engines are simple machines. If it works don't fix it.

How did you swing that price? When I was looking the electric conversion for my boat was going to be much greater than that!

Based on my perusal of some of the well-known suppliers ( like oceanvolt) , I would also like to hear more ! Repowering with a functional electric system is definitely no cheaper than a new diesel. That’s for sure .

I’ll investigate further . It looks like the top part of the bracket has been replaced. I would hope with steel . It’s definitely not the replacement new bracket design though shown in that site . Is the top part the source of the failure?
The new bracket is designed different and is necessary. If you break the timing cover you will need a new engine because that cover is not available anymore.

Yes , I noticed that after looking at it a little more closely. ( see additional photos I posted ) . It seems there are a few vendors for the bracket kit . I want to make sure I buy the right one .

I went through the Catalina store...they have the most manufactured boats including Kubota engined parts (including alternators) and keep a great supply of similar to Ericson products at a fair price.

I did a full write up of the conversion on www.sailingcinderella.com

Its not as pretty as an oceanvolt system, but it does the job.
Thanks for that reference P! Your site (and ”Sailing with Uma”) got me interested in electric power now. Actually my boat and mission are a perfect candidate for conversion because (at least for now) I use the engine to get in/out of the marina and that’s about it - so even an lead-acid solution with 4 hours of range is probably good enough for what I do. I don’t want to change the topic on the thread, but it seems like my best option right now is to keep my diesel going for next 2-3 years and in the meantime I can start researching an e-power solution.

From viewing your initial engine photo, my suggestion is to replace the air intake filter you have. It looks like a makeshift/homemade filter and the crankcase breather hose isn’t connected. Dirty air entering the intake is a quick killer of piston rings, which are key to combustion, compression, and horsepower.
Maybe what you have will suffice, but for peace of mind I’d look into it.

K&N, fine Ericson Forum air filters since, uh, 2011.

I use that one too. I put a sticker on top of the unit indicating 'K&N' and their part number for easy re-ordering.
