I want to buy a 18.5ft bowrider (1999 - 11 years old) who used to have a 220hp volvo penta engine (1.97 ratio). The guy who owns it burned the engine last summer and replaced only the engine with a 3.0 Volvo gxi (150hp, 1.97 ratio) and kept the old leg (he did not change Stern-drive Leg).

I went to ask the mechanic if the boat is good to buy because he will be my mechanic and he said:

The boat is in great condition as you can see.
The engine is new (he did the replacement last year) and that because the water coming from the leg was not enough he had to do a modification (add a water pump to take more water to the engine). In addition he says that the only error the computer gives is that the engine can not understand if the leg is up or down because some sensor is missing in the old leg and is not needed at all (this sensor is a part of the new sx driver and since it is not installed in the old sx drive the new engine gives this error that does not matter)


Is there any problem in this scenario? I dont understand anything about this things so please explain.

THANKS

Has it been reproped to compensate for the difference in HP?

You may need to go up a few inches in pitch ie from 21 to 19 or from 19 to 17.
