2000 Suzuki 150 DTC problems

[fordtrbo]

Hey everyone, need some advice on a used motor I bought for my boat. It idles fine, unfortunately it won't run faster that 3 miles an hour! It appears to be a fuel line issue, pump, filter or whatever. If I have someone squeeze the "fuel ball" in rapid motion I can temporarily get up to 10 mph. Does that sound like the fuel pump or filter? I dread sending it to my local Suzuki dealer and paying out the @#$! Thanks for any help! BTW, its not bad fuel, or a bad ball, replaced both!

test compression<br /> test spark<br /> if those to pass rebuild the fuel pump and carbs<br />if the motor sat several months its possible you have clogged carbs. its also possible the engine is so overpropped it cant turn.<br /> what kind of boat is it and what size is your prop?

Thanks Rod for responding. I have new plugs and the compression is fine. The motor sat for months, I ran it one time for a short journey and it ran rough but ok. Fuel pump or carbs? I will bet it is one of the two. I sprayed engine tuner in it the day before and it ran just fine....then I took it out to the bay in Northern California...the rest is history.

If it has carbs that is probably a good place to start if it's been sitting. If it is a 2000 however it is fuel injected and the fuel pump is the more likely candidate. If you're a mechanic go for it...if not save yourself some money and pay a professional. When you don't know what you're doing you stand an excellent chance of messing it up even more. In my 25 years in business I have countless times seen repairs that cost 4 times more than if the customer had just brought it to me in the first place. Start by figuring out what engine you have..carbs or EFI.
