specs for 18 sport
 

anyone know where i can find what the biggest motor i can put on a 1990 18 sport cc? it doesnt have the ID plate on it.....and it currently has a 1990 120 force on it..but i found a 2000 4stroke 115 yamaha that i'd like to buy ...wondering if the transom can handle the extra weight....nada.com says the force is 300 lb and says the yammy is 390lbs

I've seen em with as much as 150hp but I'm not sure of the hull's rating. You should be powered about right at 115hp in my opinion.

think a heavy 4 stroke 115 will be ok though?

Re: specs for 18 sport
 

If the transom is not rotten, it should be fine. With the force motor on there, do you notice any flex when you apply your body weight to the foot of the motor when tilted down? Bounce on it real hard and see if you notice any flex.

Kajun, I have one and its rated for a 150. *Mine is a 90' with a 120 Force as well. I have seen one with a 175 though (same weight really)

A 150 would be PERFECT IMO. Its a heavy lil boat. ;)

You will be FINE. REPOWER! 8)

you will be fine if there is no rot in the transom. Go for it

Re: specs for 18 sport
 

In other words, if the motor falls off, it must not be strong enough! Just kidding. If your tansom show no obious signs of trouble, you will likely be ok.

115 4 stroke ought to sip the fuel

Sidenote-it looks real nice, but evidently dont run so well. We happened to launch at the same spot 2 weeks later and I had to give him a tow in. ::)

According to Wellcraft's site 150hp is max.
