how much are a pair of freshly rebiult late 80s v8 300hp evinrude outboards worth?

Not Much since they had some Problems, mainly in the casting from the factory in the powerhead.

They may have some good parts now.

Just what I heard.

But I do see some still running HARD.

when I looked at my boat it had old V-8's. I talked to several people that said they WERE NOT worth the $2000.00 each that the owner wanted.

They may not be worth a whole lot , but they look like a million $
Kinda like an I/O with a big lumpy cam but has a hard time doing 50mph

I'll give you 100 bucks for them Each

I bought 2 GT300's for about 2600, they have Mayfair plates on them and open exhaust and are all stock. They can be made to run very well but had some lean out problems and are hard on lowers so you need to modify them a little and ease off the drives a little.

they are not worth much. you might be able to find a good home for them. most of the bad thing in the powerhead failures were improper fuel systems in the boats not the powerheads. i have a crap load,plus the two ryan didn't buy the customer just gave them to me. fyi

Although Ihave not had any experience with them, I have not heard anything good about them. It is also my understanding that their weight is excessive for the power they make.
