Have a 1994 Bayliner 1950 Capri with the 3.0 Mercruiser that has a couple problems.
First off, the boat is hard to start. Gas is fresh as I use the boat almost daily. Engine can be ran for 30 minutes WOT and if I shut it off and try to start it, it will be just as hard to start as it is cold. I can usually get it to start by putting it in neutral and pumping the gas while turning the key.
Second, the boat bogs down at a certain point of the throttle. It's not far after idle speed. It'll bog, but if I keep pushing down on the throttle it will break through and rev up. Does not matter cold or hot engine, it still does it at the same spot.
I believe it is an adjustment that needs to be done since we got the throttle handle replaced a year or so ago. I'm unfamiliar with boat engines but pretty handy with four wheeler/small engines, so I'm sure I can adjust it but don't know where to start or where to look on the engine. If anybody has any tips, it would be greatly appreciated!
