Late to the discussion but I repowered my 40 ft with a beta last year. Love it. To have someone else do all the work cost me about 20K

Did you replace the idler pulley too?

That single bearing cost me hours of grief.

Delmarrey, I did not replace the 2 idler pulley's, on my engine one pulley is truly an idler and the other tightens the belt. Both seemed to be in good condition, but if they a prone to go out I would consider it. I guess I realy never considered it but I can guess what would happen if one were to go bad. Realy bad stuff would happen.

About 20 years ago I had a 60hp Isuzu engine running an air compressor and water pump on my dive boat. The starter went out. It cost me $3-400 bucks for a new one - maybe more I cant recall - but it was $$$$$$! After it burned out, I decided to try rebuilding it - no one had the parts other than Isuzu.
I new a guy who worked for an auto electric rebuild center. We took the old starter, went in the back room and started pulling starters off the shelf - we found that the starter off an old Chevy 235 6cly engine matched exactly!
So, good by Isuzu - hello chevrolet! The rebuilt chevy starter cost me $35.00!
No more headaches in the starter department.
I have found this to be the case with other foreign parts as well over the years. It seems the Japs just copied what we had already engineered in some areas. I heard that the 4cyl Isuzu diesel was the same block as the chevy 4cyl gas engine that was in the early Nova! Maybe???

In the '70s I worked in a Chevy dealer parts department. There was a relationship between Chevy and Isuzu at the time, which led to the Chevy Luv pickup truck. Which was actually an Isuzu pickup.

I wouldn't doubt the Chevy block being used in the Isuzu diesel. The first versions could have likely been overstock Chevy blocks, as the Nova never sold in large numbers with the 4 cylinder. This was at he beginning of the muscle car era in the US and the V8 was quickly becoming popular in the small cars, with the 6 cylinder being a much more common base engine.

If your not going to replace, I would recommend carrying a spare. It'll give you a warning (squeal) before it goes out. I was up in the Desolation Sound when mine started making noise.

Hi Guys, as a diesel engineer I can assure you that most diesel engines, serviced properly will last for years. Lack of maintainence by the owner is the biggest threat. Perkins are a brilliant long life engine, (mine 26 yrs old). Keep it clean, get into the habit of checking it every morning and you will soon spot anything untoward and be able to fix it immediately. Keep anti freeze or coolant mixture(even in the tropics) it lubricates the water pump and cleans the interior waterways.

You the man, Rocketman! My brother says the average U.S. boater actually uses his boat 30 hours per year. Your engine may very well last you (and the next owner or owners) for many, many years to come. I wouldn't just assume you've bought a couple of years with all the work you've done.

I did knock some wood after I typed that.

Hiya Tia bu,
Yep, your right, I've cruised with my single Perkins 4236 engined motor cruiser through all the Irish Waterways, up the Western Scottish Islands and then from Ireland to France and down through the canals to Spain and back to France and she still has full oil pressure.The only time I had a hint of a problem was in a force 6/7 in the Irish sea and the oil pressure gauge flickered a couple of times. In a rough sea the oil was sloshing in the sump and some came up the engine breather, I now carry a quart bottle handy to put in if it gets rough at sea and happens again. enjoy your cruising, Good Luck
