Does anybody have a 115 on a 18'? how does it perform? Speed?

Yep-

Gotta 78 model 18' cc with a 115 Yamaslammer saltwater series.

4200 rpm is about 35 knots and wot is about 42. These will drop a little in the summer as the water temp here is about 45 right now.

Thanks! I currently have a 1995 130 johnson and my max speed is 42 mph (gps). I am considering going to a 115 or a 150 in the future. I like the 115 due to its weight since those boats are so tail heavy and the 115 are not as thirsty!

Fisher,

I've been running a 140 Suzuki four stroke on my 18 for over six months, and it is really sweet. A little over 400 pounds, just under 45mph wot in flat water, absolutely a miser on fuel, and quiet as a church mouse. Same engine is now sold re-stickered as an Evinrude, so parts and service network is greatly improved.

The nice thing about having the extra juice is that when you want it you have it. See if you can hitch a ride on a boat with one and check it out.

Good luck, bmaj
