Hello Everyone... new to the forums here and a little background. I just purchased a 86 Bayliner Capri last weekend. I am little mechanically inclined but not a techie. I also purchased the maintenance and repair manual for the Force and I should be able perform most of the maintenance outlined in the manual.

The boat had sat for about a year but would turn over and idle when I purchased it. Took it out that day and it ran really rough and had a really hard time getting the engine to get up to full power. Kept dying when I would accelerate. The few times I did get the engine up to full power it ran about 20 mph.

I changed out the plugs and it made a huge difference. Starts without any problems and the boat runs about 35-37 mph (from what I have read in other threads this is normal for its top speed) with 2 people in the boat. No problems with acceleration.

However when the boat is loaded with 5 people (2 adults, 3 kids) the boat wants to bogg out during acceleration. I have to pump the throttle to get the engine up to full power and will run about 28-30 mph.

I am curious what I should do next. I am thinking the carbs need some work but I would like to hear from those who a little more experienced than me.

Also on a side note... one of the throttle cables is a little frayed (but still functioning) but plan on replacing that soon... just ordered the parts... not sure if that has any affect on the bogging out problem.

The throttle cable is probably not affecting the bogging. Sounds more like carb issue. Pickup some gaskets and parts cleaner and give them a good cleaning. They are easy to remove and reinstall on the 85hp. Took me about 20 minutes first time I took them off. Could do it now in 5. The carbs are also really simple. When I cleaned mine, they came apart and the gaskets were reusable. But it wouldn't hurt to have fresh gasket kits.

Since the boat sat for a year, I have to ask: How old is the gas?

[poulon4747]

There was not much gas in the boat when I purchased it. I put an additive (can't think of the name) to help out with old gas. I also have gone through a couple of tanks of gas since the original purchase and I still have the same issue. I plan on working on the gas lines and carbs next weekend.

Is the boat struggling to get on plane? If so, have you adjusted the trim to account for the additional load?
