1. Bought 3 months 17.5 ‘ Boston Whaler Outrage 1996 with 2003 150 2 Cycle Yamaha outboard
2. No problem when I bought it, tested in Pensacola bay for 45 minutes
3. I took out 3 weeks ago and as I left the no wake area and went to almost full throttle it died.
4. I could crank again and limp back to boat dock.
5. I noticed that primer bulb was compressed when it had died.
6. I opened up floor port and checked the anti siphon valve and it was blogged.
7. I cleaned out the anti siphon valve with compressor, check for any obstruction in the line.
8. I also removed and replace the Gas/water separator and install new filter on it.
9. Once again I went for test run. I ran engine for a good 30 minutes, WOT, half throttle and idle speeds with no problem.
10. After @ half hour from idle to half throttle it would hesitate and then take off. I was back to same problem.
11. It did the hesitation for the next ten minutes every time I would try to go to half or full throttle
12. Finally it started missing like being starved for fuel again, even at idle speed.
13. I then took an external 6 gallon take, by-passed the gas/water separator filter and went directly into the engine.
14. I again had the same hesitation problem.
15. I checked the anti siphon valve fitting again and it was not blogged this time. I was guessing maybe what ever was in the tank had also worked its way up into the motor mounted filters (three each).
16. I took it to a Yamaha outboard mechanic at this time and I am having the filters replaced on the engine.
17. The mechanic said there was gunk in the on board fuel tank and they thought the fuel tank would have to be removed and cleaned
QUESTIONS:
18. Is there something I can do also before I go removing the center steering wheel console, and the deck to remove the gas tank?
19. Should the Gas/water separator be catching any gunk and debris if it was still coming from the tank, before it reaches the other filters on the engine?
20. Would a product like sea foam be worth trying or will I just plug up all the filters again so they have to be replaced?
