where i currently occupy space, the easiest engines to find parts for are perkins and tohatsu. they propel forkilfts, tractors and buses.
mercedes benz also for bus propulsion

Re: Which engines would you think twice about

IMHO, if you've got a choice, get a Yanmar. I've had them on 2 boats and never did anything to them but oil/coolant changes and impellers. They were rock solid for us YMMV.

We've had a couple of fresh water cooled Westerbekes and a raw water cooled Volvo. Made them both work (I would not take them out of a boat, or eliminate a boat from consideration that had one), but they were both more trouble. Seems like we were always fixing some little thing, but with attention they were reasonably reliable. Volvo was definitely the hardest to keep running, but it was raw water cooled, and 20 years old, so who can complain?

Re: Which engines would you think twice about

I have to put in a shout for the Universal diesels based on Kubota blocks. I have just completed a complete rebuild of a Universal 5416 (16hp 2-cyl) and was able to get 90% of my parts from Kubota tractor dealers for very reasonable prices. These Kubota-based engines have a good reputation for reliability, which I'm hoping is well-justified. My rebuild was a little over $2K including machining, which translates to 25% of the price of a new engine.

I also had an Atomic4 for 8 years. Sweet little engine. Replaced oil, plugs, points and checked timing every year. Never had any other issues.

Just My $0.02.

Just to document the pain of owning a Volvo; A friend had to replace the thermostat for his MD7a this summer - it cost him $90

Re: Which engines would you think twice about

i have the Perkins Prima 50; somewhat rare engine but starts every time so far. Starts reliably on the coldest days.

Not sure of the similarity of Volvo and Perkins; ??? I have a volvo parts book that matches the engine for the most part.

Maintenance Parts do seem to be somewhat cheap when bought other than perkins. I had it out of the boat 3 years ago and discovered that Perkins is a very popular engine. They are used in Massey-ferguson tractors, Caterpillar skid steers and many commercial generators. I had mine taken apart (head cleaned of coke, injectors checked, bottom end checked) and tuned up at the tractor dealer for $1k. I consider that fairly cheap.

By the way; even anyone knows where i can find a Perkins Prima 50 Repair manual, just let me know. (nothing on-line, i know)

Re: Which engines would you think twice about

Wow page 7 on marine diesels before there is a mention of Perkins.

4-108 in my previous boat and 4-154 [Japanese version] in the current one.

Widely used in a variety of apps.

Some 4-108s driving pumps/generators have made it past 50,000 hours untouched except for routine servicing.

I'll never buy another one, that's for sure. Limited distribution, and they are selling you a common part available at any diesel shop but at 8x the price and trying to obfuscate the more common part #s

Because they own the majority of the inboard power boat business. I am sure there small diesel portion of there business is in the realm of single digit percentage. I would be willing to bet that most of the Volvo Penta shops don't work on diesels at all, or only do it grudgingly.

Re: Which engines would you think twice about

Rarely need parts but our local shop in Sidney (Klassen Diesel ) has good inventory and no trouble ordering stuff when they solved my problem of injesting water while running. I've looked at Izusu dealers in Thailand and Malaysia and found them well stocked. Make sure you've got all the part #s correct .Marinized bits by second party may be a different story.
