I have been looking to repower my 15' 1987-88 Sport from a 30hp. I have searching since Fall '03 to trade in my 30hp Yamaha (same year) & have recently found 3 motors. A '95 Yamaha Enduro 60hp, '87 Merc 80 hp, & a '90 Merc Force 90 hp(all from same dealer) Any opinions, suggestions, or comments? All are welcome & thanks in advance. Any ball park quotes on what I should get for a good working 30 hp?

The 15' is max rated for 70hp. I think the first year max hp was 75hp. Out of the choices I would go with the 60hp. That hull would be too "squirlly" with the other two. I'm running a '84 Johnson 70hp and it sits a little lower in the back than I would prefer.

I would guess the motor value in the $1000 range from what I've seen in this area. People seem to prefer tiller handle configuration for their jon boats in that hp range.

I think that 90 HP would be a bit much for this boat. I'm not afraid of speed, mind you...but there are moments that I fear for my safety with a 70 HP maxed out and trimmed...there is not much more than a couple of feet of hull in the water with 70HP.
I know there is a photo of one on Cetecea with a 90 on the back...but this boat is already a bathtub with a tornado strapped to the back with 70. The performance of the 60HP will more than double the enjoyment that you got from the'll hit the high 30's maybe 40 with a light load and smooth water.

Few things....1st try another dealer.

2nd that 90 is a Force....NEVER buy a Force.

3rd that 80 is WAAAAYY too heavy for that hull.

4th the enduro 60 is your best choice being you keep your controls, key switch, tach, etc which new will run about $1000.

5th if that 30hp is the 2cyl she is worth about $600-1000. If a 3cyl, more.

I agree with everything Bigshot said. A 60 is plenty for that hull........and don't buy a Force. You will save money on the front end but lose every bit of it and more when you sell it.

Used to have a 1978 15' with a 70 hp oil injected Yamaha 2 stroke, (228 pounds). It was an excellent motor for that 15. Ran great, plenty of power, handled well, good balance, easy on gas. That rig always felt just right. I don't know what you have inside but mine had the GLS interior mounted slightly forward with a 14 gallon tank under the seat. Not long ago I talked to the guy that bought it from me several years ago and he says the same thing. It's a well matched boat and motor.
