Volvo 5.7 engine. Good or bad?

[Matt1021]

I had recently came across a boat with a 5.8 efi Volvo engine. Some guys on here advised to stay away from this engine since parts for the fuel engine were no longer available. Seeing a lot of Volvo 5.7 engines. Any such issues with 5.7 or should I stay away from this also?

Did you read this post in your other thread? https://forums.iboats.com/forum/gene...5#post10833685

Nothing has changed in 17 days. Stay away from a Ford motor in any boat as there are no parts, especially an EFI motor.

A 5.7 is a GM motor with plenty of parts and service.

the 5.8 is a 351 ford motor. Ford got out of the marine business shortly after (well over 20 years ago). hence the reason that there is no support for the fuel system.

the 5.7 is a 350 cubic inch GM gen 1 motor. there must be over a million in boats alone, not to mention the billions on the road. parts a plenty for the 5.7 for the foreseeable future.

If its 10 years old or older, I'd get the model number and look up on the V/P website (connected with iboats) to see if key parts are still available such as:
EFI electronic control unit
fuel pumps
Electronic ignition control unit

these are things that will leave you high and dry if they fail and you can't find replacements.
I've said this before, but this is the advantage of carburated engines that can run with a carb rebuild kit + cleaning, the stuff is all over the aftermarket and in the case of Holley and Edelbrock, new stuff is widely available. That leaves the ignition system where the electronic Prestolite can be replaced with a Delco EST. Worst comes to worse you replace the EFI stuff with a GM marine or Edelbrock intake and install a 4bll Edelbrock or Holley (will also have to convert back to a low pressure electric fuel pump) and an EST distributor. No more worries.

Lou C, I understand your thought process.....but not really an option at this point. Way to much technology and expensive parts to eliminate & replace to get back to a basic carb motor.
I'm beside myself trying to figure it out. When it's under 160* it purrs like a kitten, but just over 160* and it starts lopping its idle. If I advance the throttle ever so slightly, it runs smooth & never it never has any issues when in drive putting around or when on plane,,, only at idle when its in neutral.
