Brainstorming for an Ocean Pro 175

[supcoop]

Well there is good news and there is bad news. The good news is that I found what caused the problem in the first place. I have two tanks fed to a tank selector switch that had clogged up and stopped providing fuel for the boat. I lost power very suddenly and the motor died because of the starvation of fuel. Yesterday I bypassed the switch and am now running the fuel line for one of the tanks directly to the racor/motor and can now get a pressurized fuel line. The motor will start and idle (a little rough) but will not take any gas at all. Causes the motor to shut down. Will be checking the cylinder walls today just in case. Let me know if anyone has any ideas as to cause. Thanks

anyone... or even questions that may lead in the right direction???

If you had a clogged switch(which you bypassed) I would strongly suspect more particle contamination in the fuel system, check the fuel filter,not familiar with that motor if carborated, sounds like particles plugging high speed jets

[Draggin' Bait]

I agree -- check the fuel filters. Also, is the fuel tank vent open? (I know -- usually a dumb question but I missed that one once).

[supcoop]

Vent is open and the fuel system has two filters on it. 1st is a racor fuel water seperator and then there is the standard one at the motor. Neither filter has anything in it. Not to say there isn't something possibly in the carbs but it just doesn't seem like that is the case here.

The motor will start and idle (a little rough) but will not take any gas at all. Causes the motor to shut down.



When you say it causes the motor to shut down, do you mean it dies if you squeeze the bulb while it's running, or that it dies if you advance the throttle? (Sounds like the latter?) If the latter, it sounds like a clogged jet; if the former, it sounds like a sunk float or a whisker in a float valve. Have you tried having someone pump the bulb while advancing the throttle? Or just pump and hold the bulb with the motor off and see if it holds steady pressure or pumps gas to overflow the carburetor?

How do the spark plugs look? Any chance you backfired and blew a reed valve or a plug electrode (or worse) when it leaned out and died?

after you run the engine let it idle as long as possible
10 min if it will, then try raising the rpm till it fails

at that moment squirt a small amount of fuel down the throat of the carb, if Im right the rpm should begin to attempt to rev up....if so its fuel starvation rebuild the carb

[supcoop]

Weel I was right but am not happy about it. It wasn't a matter of what it sucked up but more what it did not suck up, as in fuel... more precisely fuel with oil mixed in to it. Truly amazing how fast you can scorch a motor when it doesn't have any oil in it. Leaned out and burned up number 1 and number 3. yea boats!!!

So sorry for your loss, supcoop. :depressed:
