My slip neighbor had a Proline 25 WA that had a pair of 200 hp Mercury Mariners on it that were always leaving him stranded. Frustrated, he decided to repower with twin 200 Hondas...
The good news was that the new Hondas were silky smooth, great on fuel, and quiet.
The bad news haunted him until the day he sold the boat.
The Hondas were so heavy that the motor bracket was awash, even when the boat was at rest. If he put more than 50 gallons of fuel in the boat, the rear scuppers were underwater. 2 people fishing in the rear of the 'pit always had wet feet. Ping pong ball scupper covers helped, but didn't eliminate the problem.
After the repower, the bottom paint line had to be restruck, raising it to the top of the bracket in the stern. Graphics were removed and replaced to compensate.
One motor ran flawlessly, but the other had electrical gremlins right from the beginning. Not sure what the actual cause was, as many parts (including the computer) were replaced under warrenty, but he eventually got her running well.
During the second year of ownership he started having issues with corrosion, especially in the area of the tilt and trim motors. Not sure if the corrosion was caused by faulty parts, or the fact the motor got a constant salt bath due to the 'low rider' stance.
Tilt and trim was replaced on both motors. One at two years, the other at three.
Boat was sold, and last I heard, the new owner was asking for advice on adding a larger motor bracket with more flotation to get the stern up out of the weeds.
The mechanical problems my neighbor had may have all been related to salt water damage, on a boat that was never designed to carry that much weight. Most people who own Hondas report good experience mechanically, but I have read that some motors have experienced corrosion issues (THT and TF).
Unless I was buying a new boat that was designed for motors this heavy, Honda would be my last choice.
Reliable? Yes, but at a cost.
Look at the wetted area of my neighbors Hondas next to my Yamaha.
These are both 25" shaft motors...
