Need advice on purchase

[Skools Out]

those are good motors but they do have computer issues from time to time. The fuel pump is most likely leaking and causing the idle issue. check compression and see if he will lower the price alot. wouldn't pay more than $5500 for it especially as it is with the idle / fuel leak.

Get us the compression test results an also hand prime it with the hood off and look for the leak. it will show up while being primed.

Compression is above 200 on each cylinder according to owner.

Good advice on removing cover while priming.

I thought of offering $6,000 since this V20 is as good as any I have looked at in the past 2 years.

Thanks much for the input

Not sure about your year but my 93 Ocean Runner 150 left me hi and certainly dry. The rings split on mine basically making the engine worthless. They are notorius for this but not sure about that year. I would def. research it though......

Offered $6,000. Offer rejected. Don't think anyone will offer more.

Been looking for V20/21 for last two years. Sure wish this boat had a Yama or Merc on the stern.

Thanks a bunch, everyone, for the feedback.

if that engine has 200 psi on the compression test, someone is lying or needs a new compression tester(should have been in the 120 range). I'm not a big fan of those engines although some people like them. Keep in mind, they were not made for very long , have a history of corrosion issues, and a lot of engine components are no longer available, from any one. i wouldn't have gone any higher than $5000. I'll go ahead and fly the flag on this one

100-120 sounds about right, 200 would require 116 octane and a whole lot of other things to go with it. They had a pretty good production run I thought being built for 14 years. Not a long run like the MERCS V-6's though. The optic sensor for the igntion system is a problem area as many will attest. The HUGE downside to them was they were THIRSTY PIGS! For a 150 they drank as much fuel as most 225's at cruise. I think $6K was more than fair for a V21 in excellent shape with a not so great engine, if anything it was quite a bit to high. If the owner isn't willing to negotiate on a boat he KNOWS needs work, then I would walk.

My factory-trained mechanic said the compression numbers should be within a few pounds of each other-- which is more important than the number itself. He declared my old Evinrude 150 in "new" or recently overhauled internal condition with compression just over 100# in ALL 6 Cylinders. If one had been several pounds lower, that would have indicated problems with rings or valves, etc.
