I bought a boat with a 1987 dt175 on it last summer. Ran terrible so after pulling the heads off I discovered water in 3 out of the 6 cylinders. Several cylinders are scored really bad. I am not sure what to do as it is kind of hard to find parts for these and I have not found a top end kit...
I recently bought a 21' seebold eagle with an 87 dt 175 on it. It has older black gauges with blue lines on the face. The boat has the zuki monitor and trim gauges already the rest are mismatched. I found and purchased matching tach, speedo, volt, and hour meters already..... JUST NEED THE FUEL...
