1979 17ft. Crestliner 90hp. Johnson...question?

[Raymond S.]

A guy here at work has a 1979 17ft. Crestliner (welded, not riveted he said) aluminum boat w/ trailer and an '85 Johnson oil injected 90hp. motor. I haven't seen it yet, he said it's in good shape. Said the trailer is in good shape, he pulls it to Ludington every year.
Is there anything about these particular motors or this particular boat I should be aware of.
Just fishing for some info...any help would be appreciated.
Thanks,

If this boat yanks you to the left you could weld it to the one you have now, and you could go fast and straight-without being the worlds strongest man.;)

Don't be stupid, everybody knows that would never fit on a trailer that way. :dizzy:

I have a 1976 sea nymph with a 85 or 86 johnson oil injected 60 horse.No problems with the motor runs like brand new.My buddy had a 50 horse early 80s johnson oil injected he disconnected the oil injection for some reason. (he sold boat last year)

That V-4 a good time tested design, they had some problems with some of the early VRO pumps and a lot of people took them of and mixed there fuel for piece of mind

crestliner is one of the 1st to make welded AL boats and are seen as a very good boat. we have Two crestliners and would say they are both very trouble free .

Tonga, wasn't that the mill that was breaking hollow drive shafts?

[Raymond S.]

I didn't realize it was welded until he mentioned it the other day.

Tonga: You said they had a few problems w/ the earlier VRO pumps, if this is an '85 motor would this be considered an earlier model or one where the bugs were likely worked out of it? I assume you are saying the early '80's motor that Krause is referring to would be the ones w/ possible problems...correct?
Also, what kind of power would this thing have. Meaning a 90hp on a 17ft. welded aluminum, estimated top speed. I may be mistaken, but when I think of a welded boat vs. a rivetted boat, I just picture it weighing more. Maybe for no reason, but I think of a couple welded jet boats that I've seen around and they seem to weigh a decent amount.

Thanks for all the help.

As I recall most of those Crestliners back then were Modified Vees, I would expect it to hit in the upper 30's, maybe even very low 40's with a real light load. They aren't any heavier than a comparable riveted boat. If that a Super Fishhawk, my old 1983 was a .010 hull, bottom and sides. The jet boats are generally a lot heavier gague, as they are built anticipating some log and gravel grinding.

I didn't think of that. That makes alot of sense.
