Cons: Expensive, Power head design flaw, Mercury has no apparent integrity
Summary: I bought one of these new, and now am trying to save you the heartache, 5 figures of hard earned money I paid for this engine and with no warning at all the motor just went. They are well known to do extremely bad in cold water. This ... read more

Pros: good fuel economy
Cons: breaks down a lot, burns coils up and service takes forever.

Pros: very happy with this engine on my 18 1/2 foot Larsen Ski/Fish.
Cons: need a stingray to improve hole shot.
Summary: Have only had one problem with this motor and it was caused by letting my wife load the boat. Didn't raise the motor enough at the sand bar and plugged up the leg. McGoverns Marine compounded the problem by charging me for a repair that they didn't do. ... read more

Pros: When it does run, it runs quiet and clean.
Cons: Unreliable and totally unserviceable by the owner.
Summary: I've had the Optimax 115 for two full and one partial season now and it's already ruined three vacations. First, it blew a rod and the powerhead had to be replaced, then the alarm chime started sounding continuous beeps and it wouldn't rev beyond 2000 ... read more

Pros: Great fuel economy.
Very low noise.
Cons: Optimax oil is more expensive than standard 2 cycle oil.
Summary: The 115 Optimax pushes my 18 foot Tracker Tundra fishing boat at 45 MPH with a very good hole shot. The engine gets incredible fuel economy and uses very little oil. I filled my 40 gallon tank up with 87 octane fuel and now have 10 hours on the engine ... read more
