Re: Starting All Over
First of all,
Thanks to everyone who is trying to help. I really appreciate the effort.
Now for a little history,
1.Bought the boat a few months ago (first time boat owners with absolutely no experience when it comes to outboard motor).
2. Took boat for a spin because we didn't know any better. Max speed around 10mph gps.
3. Bought manual and searched web and found Iboats. Quickly joined.
4. Replace spark plugs and tilted motor a little aft of boat because we felt the motor was a undersized and having a hard time getting the bow out of the water. Boat took off initially, hitting approximately 28mph gps. Motor then preceeded to bog and noticeably lose RPM's. Thought it was water in the gas because it took off once again a little later but then fell on its face once more. Limped back to shore.
5. Replaced fuel pump. Don't ask me why. I read something here it seemed like it would help and the fuel pump was original. Made no difference.
6. Took to shop because we were out of ideas. Mechanic found that the low speed needle valves packing was gone and needles had backed themselves out so much that it was actually flooding out the motor when trying to get WOT. Initially, this seemed to fix it, we got up to speed and on plane for a good 45 minutes and brought it back to shore. Next time out, motor bogged when trying to get to WOT. What happened?
7. After advice of everyone on Iboats, totally dismantled, soaked, cleaned and blew out carburetors. Rebuilt with new carb kits including new floats. Replaced all fuel lines. Was so sure that would do it, but nope. Maybe hit 10mph again and very clearly not hitting RPM's like it did in the past.
8. Crack in one of the ignition coils. Checked spark with spark tester on both coils and both seemed OK. Was advised by a few members here that ignition coils are known to go bad at high temps so I just replaced the cracked one. Retested with spark tester and jumped a 3/8 gap with strong blue snap on both coils. Went to ramp and still no RPM's at WOT.
9. Did a Link and Sync according to Joe Reeves timing at WOT. Found that the timing as found was firing at about 25deg @ WOT(21 +4). Adjusted spark advance at WOT to 15deg (19-4) using Joes method. This surely had to be the problem right? Wrong. Took it out and still now RPM's under load.
That's pretty much where it sits now. I'm just about out of ideas. By the way, sqeezing the primer while running does nothing. By the way, each time the motor was tested in the water, the plugs were removed afterward and found to be wet and oily in most cases. That is why I thought the motor was running rich.
I'm sure I'll think of a few other things I did after I submit this post, but I'm pretty sure I hit all the major ones.
Once again, thanks for any help or suggestions you can give me.
