200HP Mercury on 1983 Diplomat, is that ok?
- Thread starter rotax21
- Start date
Designed and legal is two different things
The boat is not 'legal' with 200 hp because of it's size. But Checkmate built that boat structurally to handle a 200 hp motor on the transom ( as long as the transom was properly taken care of over the years).
So yes, the hull should be able to handle the power, but the boat can be dangerous if not properly set up and driven by an experienced driver. And if you get pulled over for inspection, you may get ticketed for running a boat less than 19' with a 200 hp motor. Is the USCG plate still on the boat? Should be near the throttle.
Rule of thumb (and yes, there's other factors involved, but this gets close):
16' boat gets 120 rating
17' boat gets 150 rating
18' boat gets 175 rating
19' boat gets 200 rating
20' and above is unlimited horsepower per the coast guard. Manufacturers will typically give a top recommended horsepower at that point.
Your hull was rated for 150 horsepower.

You dont have to pass on it if you REALLY like the boat. You could sell that 200 to someone here or on Screamandfly.com for a LOT more money than you'd have to pay for a similar year but smaller horsepower engine, like a 125 Merc. You could get that boat, sell the 200, install a 125, and put $$ in your pocket...........
