I have just got an 85 bayliner capri for free. The boat last ran in 04 and was put in a shipping contaner for storage. the guy was about to trash it. The boat is in good conditon, every thing is clean the trailer still looks bran new. any way checked comprsion ok. spun fine by hand with plugs out. fixed some wiring and motor starts up. the problem i have is there is alot of oil comming out of exhaust. looks like a james bond smoke screen. will not idle try adjusting but to help. did noitice bottom spark plug was loose. that plug was fowled top one ok. model is a force 50 hp model #507x5a. the other thing was on drivers side of carb there was a little fuel every so often spiitng out and some fuel by choke plate. any help would be great

Re: lots of oil

A boat that has sat that long will need a fuel system check. Go through it from tank to carb with special attention to cleaning.lots of smoke on the muffs is normal and some residue is normal.However you surely have a flooding problem which would increase both.
You should also replace the impeller before doing any serious boating.
Cheap insurance from overheating.

Re: lots of oil

If the boat was fogged before storage, you will get alot of smoke on the first start. There are a host of items that you should do on a boat that has sat for a few years. Here are a few.

1. Buy a manual for the engine and boat if you can find one. Fleabay is a good source.

2. Change out the trailer tires. This is cheap insurance as they may look good but fail at 65 MPH.

3. Change out fuel and clean fuel tank and lines.

4. Disassemble carbs, clean and adjust from the baseline.

5. Change fuel pump diaphram.

6. Did I mention to buy a manual?

7. Check timing of trigger and idle cam

8. When reassembled, ground spark plug leads and check cylinder compression. Also look inside cylinders and determine if engine needs to be decarbed. If so, see step 12..

9. You did buy a manual, right?

10. Mix up some fuel and add to fuel tank. Pump up to engine and look for leaks. Make sure that the ball gets hard.

11. Start engine and run at fast idle until it warms up. The smoke should start going away. Next try to idle the engine. Don't worry about it at this point if it doesn't idle well.

12. If the engine needs decarbing, now is the time to do it. Follow the sticky and you will be all right. Change out the spark plugs after the decarb job.

13. When you get on the water, tie up to the dock and adjust the idle while the engine is in forward gear. Adjust it to about 700 to 750. I suggest you use a induction tach because Bayliner tachs jump around alot.

When you are out riding around, check your battery box for water. If you find some, you could be overcharging and should replace your rectifier with a regulator, see sticky.

I'm sure there are things that I left out but others will chime in. One last thing, put the manual where you can find it the next time. (there will be a next time ;))

Regards,

John

John 'nailed' it!

But he forgot to mention, that you will need to get the manual....

Steelespike was 'dead nuts on'...about replacing the impeller. This is a MUST! Any impeller that has sat that long...even if still in one piece...will have taken a 'set', and not perform as advertised.

Enjoy that Bayliner!

Re: lots of oil

thanks for the info, order the manual and in process of taking care of fuel system. What a pain ordering right carb kit for this motor. Was able to talk to a good parts guy at local marina. Lots of good info. Also learned not to order any parts from napa they had no idea. By the way order the manual.
thanks once again for info.
