CONTINUOUSWAVE

No on the plastic, The boat was damaged from Hurricane Michael, three oak trees on the boat shed will do that. I had to cut the stern light into pieces to get it off,

Nut sent off to Jim

I have the knurled locking nut for the pole lamp from a 1969 Nauset. The boat was damaged in hurricane Michael. I have no use for the knurled lock nut. If anyone wants it let me know, and I will mail. Otherwise into trash can (which I prefer not to do)

Thanks

I have a 1972 13-footer that needs a "newer" engine. I have been looking for a Yamaha 30-HP two-stroke-power-cycle engine. Almost every engine offered out there is a 20-inch-shaft model. My 13-footer needs a 15-inch-shaft engine. [How can a 20-inch-shaft] engine [be fitted on a] 13-footer ...

Having done a few boats in Florida, I may suggest the following: --the boat would be titled and registered as a boat "Never titled before since it did not have a engine." --a letter from the previous owner and seller stating the boat was never titled or registered since it was "a tend...

Okay better run this morning.

Air silencer cover off, hood on. Back throttle slightly (maybe 90% throttle). Boat does 27.5 mph with minimum laboring or surging.

I think I will try changing out the high speed jets, easy and cheap check.

Thanks

Okay, Thought I had it the last time I worked on the engine. Took it out for a Marathon run, and it was still doing the same thing. Light surge, loss of power, laboring sound out of the engine. I was out of ideas, so I ordered a heat stik, to check if the engine was overheating at top throttle. Ther...

Okay, Think I got it licked, the minor fuel starvation that resulted in only 90% power being available at WOT. I moved the older OEM 1974 fuel pump over to the 1976 engine, Nah, things were actually a little worse. SO put the New Sierra pump back on. Then I just went through the powerhead, Make sure...

Okay, Did not want to wait three days, so.......pulled one of the old coils out of the trash can, Installed the old coil in place of the new but bad CDI coil. Down to the lake, It now runs on all three cylinders. Yeah. Initially I had some light surging (please see my original message) but that stop...

PS: Just tried something, Went out started the engine at house in idle, on muffs for water. Shot aerosol sea foam into number three carb, no effect. Shot sea foam into number two carb, immediate bog out. So just a double check, it definetly seems number three cylinder is the problem. So.....double c...

Okay, Pointer missing on engine, Not a insurmountable concern, just take the pointer off the 115 Johnson and move it over. The pointer is just screwed in. But in meantime.......once more, pulled all carbs, examined, all look good. Took the boat to the lake, this time bringing someone to steer. Air i...

Okay, I am missing something here. Now I have an engine that will only give me about half throttle, and wants to bog down and quit when I go to full throttle. Idles fine though, starts right up. So the latest in the saga: Remember I had no spark on number three coil, so I took it back to the shop th...

Thanks JIMH, A much cleaner way of outlining the steps. The only thing I have not checked is moving the A1 (number three power pack wire) to B (number two cylinder coil) and see if I have spark at number 2. If so.....no way around it, bad coil. Or possibly bad ground on the coil, I will check the gr...

Okay, latest and not so greatest: Got the boat back from the shop, they fixed the mounting bracket for the coil on the bottom cylinder. The shop mech said, "by the way you have a bad power pack." II ordered a used power pack, put it on, and no change; major loss of power. See last test run...

Thanks Oldslowandugly, your post is where I am. Thanks for the post. I will keep you informed on the continuing drama. I do have a full OMC factory manual. I was just being lazy, and ending up making more work for myself. I should have pulled and cleaned the carbs first. I found this afternoon that ...

The latest: To oldslowandugly, I never changed out the fuel pump, maybe I should have since......... Yesterday, (after the engine ran well for 10 mins) I went out for another run, The engine at first ran poorly, then ran good, then ran extremely poorly. At the end it was like one cylinder was not ge...

The results of test run: the engine ran great, the best it has since I mounted it. I am not sure exactly which part made a difference. Here are the steps since my initial posting last night: --the three-way fuel supply was pulled off and checked for obstructions; none were found; --before putting ba...

Thank you all for the quick replies. I was starting to think I was off base in believing [the cause of the problem] to be a fuel starvation problem I re-checked the carburetor synchronization, and it looks good--right on the mark as per the manual. The current fuel pump is a Sierra aftermarket pump....

For all the older model OMC Wizards: I have a 1976 Johnson 70-HP in-line three-cylinder outboard engine that will not maintain full throttle. You can back the throttle off to about two-thirds-full for a couple minutes, then go to wide-open throttle (WOT). When you first go to WOT, the engine takes o...
