NYMack,
Sorry about all your troubles. I haven't been on in a while so I thought I would check in with yall. I don't see that anyone answered you on your compression check question.
You should have all the plug wires removed and be at WOT. Everything I read said to make sure the wires don't arc back to the engine, so I put electrical tape on mine. There is a ton of info. on it if you google it. Looks like you found your problem though.
As for me..my transom repair is still in the works..lol..I spent all the money I had saved up on dirt bikes for me and my kids because I didn't think the state of Georgia was gonna register the boat. Well, ..they registered it..now I gotta save some money back up and re-do the transom amongst other things. I'll be checking in on the site though.
I missed the t-shirt sales again this year..thats crappy. Be good.

Thanks guys for all your help, I decided to replace the power head with a re-build.
I am now using this down time to replace all the little things on the engine that is old or that I think will enhance the longevity of the new motor like all the check valves, flame arrestor hoses, reeds etc
Hopefully all the parts are here this weekend and I will assemble it.
In the mean time I am helping a friend restore a condo, finished the tiling and moving on to hardwood floors.

[nymack66]

Its all bolted up, However I ordered some reeds and one set is missing halted the rebuild this weekend I am so pissed.
Question on the fuel mix for the break in period any ideas ? 50-1 or 25-1 ?

[THEFERMANATOR]

40:1 would be fine for the break in. Also go easy on it for the first 30 minutes or so, she will be running HOT when she is burning the assembly oil off and the initial ring seating.

My best advice about BOYESENS is DON'T RUN EM! I ran a set in my 225 and got about 5 hours out of em before it started coughing at idle. Get a set of Tony Doukas reeds and be done with it for good. Also be ABSOLUTELY certain which reeds you have as 85 and some 86's had the oddball reeds in em.

Ferm, The reeds I purchased is BOYESEN PART# B146 Petals: 6 (Stock reeds removed 6 petals)
Base on the above information which reeds do I need to purchase from Tony Doukas ?

[THEFERMANATOR]

I believe the 6 petals are the standard style. Give him a call and he will know which ones you need. The TDR reeds use the factory hardware and reed stops, so make sure you save those. I know the TDR's idle better than stock, but not as good as the BOYESENS's do for there first hour of run time(after an hour of running my idle started slipping down). The throttle response though from the TDR's is UNBELIEVEABLE, and the power is smooth since they are single stage reeds. I know my engine used the 103's, but this was a 12 pack of reeds.

my 87 Evinrude 140 had a set of Boyesen reeds they worked great in mine never had the first issue but break them in as the directions tell you too.
