I think you'll be fine with the merc but do check with your insurance company. 1962 Custom 1989 120hp Evinrude looper

As with anything, common sense always prevails. Have fun and let us know what you end up doing. Cliff 1966 13' Sport with a 1993 40hp Yamaha 2 Smoker

That being said I just changed to a 90 Yam 4 stk only because I just thought it was time. I sold the 115 in about 15 min on craigslist for $900. 1996 Dauntless 17 DC - 115 Johnson Ocean Runner

The boat can handle the weight and the HP. The boat should run 50 MPH and at that speed, you have to be careful with a Montauk. I run a 115 HP engine on mine, but it only weighs 300#.
