I bought this boat five years ago and only used four or five times each summer. Has worked fine in the past though at a top end by GPS of only around 42 mph seemed a bit slow on calm water. Since I have owned it, I have never had a real tune-up done. When I bought the boat, the prior owner had just recently completed the 175 conversion but other than that, I have no idea what he had done for upkeep.
This past summer after sitting for 10 months in the garage, I took it out. It started fine. But when I tried to accelerate, for the first few minutes it did fine taking me a mile from the slip all over clear deep water. Than it slowed down. Though going slow, the engine sounded normal at first as it slowed down making me think it was cavitation. Heading back to the slip I had to nurse the throttle to keep it running at maybe 5 mph. If I advanced the throttle too far it would stall and not immediately restart. After a minute stalled, I could get it to restart and it went back to the slow speed, but normal sounding engine mode.
My question is; does this sound simply like a cavitation problem, or motor maybe needing a tune-up or some other problem?
Also, would the 42 mph be normal for a 175 engine when running normal, or should I look into upgrading the impeller or other parts?
Any help would be appreciated.
