I have a 83 Bayliner Capri with an AQ125a and 270 out drive. This is my first boat and I bought it last year. It has always had an issue where it seems to have a dead spot between 1400-2000 RPM where if I accelerate slowly it will bog down and die. If I punch it the engine revs right up and I can be cruising at 40 MPH without an issue.
I did a carb rebuild with a kit from Mikes Carbs. last year but it didn't seem to help. I have tried adjusting the accelerator pump too but that hasn't helped either. I figured I either didn't do a good enough job cleaning the carb (it was pretty clean when I rebuilt it) or something else is wrong (maybe accelerator pump spring is going, etc) and I was planning on trying to get a replacement carb this winter or taking the current cab and doing a full dip in carb cleaner.
However, I'm now wondering if it is something else. I was on the lake this weekend and I had the boat to myself and I discovered I can move through the RPM range with no difficulties if the drive is in neutral. It only bogs down when it is in drive. Could there be something else causing the engine to bog down? Could a damaged prop do this? I serviced the outdrive last fall so it has fresh oil. The old oil was clean and looked new.
Thanks!
