Just purchased boat (used), 1976 24' bayliner Skagit with a 350 omc and volvo 280 outboard, edelbrock 1046 carb. Previous owner stated that the engine bogged when throttle was applied, he had messed with the timing thinking that was the issue. After that he could not get it started. I was able to get it timed and running again, set at 8 deg. as stated in the manual #27 from bayliner. Took it out to the lake with wife and another boat for safety along with several extra fire extinguisher, not know the boat and wanting to make sure that it was safe. Oh, forgot to mention that I was able to get it running in the back yard using a 100 gal trough and lower the outboard into it.
Once on the lake, found out the praws did not work in reverse, (another issue), but engine bogged when throttle is applied. I have read all of the forum posts looking for any that posted the answer to their problem but was unable to find it. Many stated fuel problems so I tried this;
replaced the siphon tube in the fuel tank, replace all fuel lines, installed a backup pump, had mechanical one connected when heading to lake. I removed water separator, and fuel filter, replaced fuel filter with new one. Started great, idled rough for a few minutes then smoothed out as it warmed up. Started increasing throttle in forward engine rev'd up fine until about 2k rpm then began to bog, never reached plane even with WOT, and revs never really increased to 3k or above. Sounded like it was starving for air more than fuel.. switched to electric fuel pump (to rule out failing mechanical pump) started forward again, increased throttle again, same problem. Removed siphon tube from fuel tank, stuck hose directly into tank, started and tried again, same issue.
I have spent a lot of time reading posts and forums about engine bog and that is why i took extra precaution the first time out.
I also read several posts about props, and although not in pristine condition, no edge damage, but paint is cracked along edge of prop and flaking back, I ran my fingers along the props cutting edges and very little ware. Could the prop be causing all of the bogging or if not please give me some idea as to the problem...
