    Timing Light Question

    For my rebuild I bought the Innova timing light model linked below, which has the built in tach. I was having a hard time figuring out why, while using this light, my idle would not go below ~1100 rpms in neutral (in tank) even though I had back the throttle cam all the way off of the eccentric...

    Piston travel

    This came from wikipedia page called "Piston Motion Equations" so take it with a grain of salt. But you could possibly use the equation below to find x and then subtract that value from I + r to get travel from TDC.

    1994 Force 150 HP - Stalls out when in idle and when shifting into forward or reverse

    This is the idle adjustment screw on my 1994 70HP. I would imagine yours would be near identical in looks and location.

    Opinions Wanted on 1988 Evinrude 9.9HP

    There is a 1988 9.9HP Evinrude longshaft for sale locally for $450 I am interested in. The owner states it has sat for a couple of years since he last used it when he sold his boat it was on. Supposedly it ran good prior to storage, started on first pull when removed from storage, and seems to...

    Link & Sync and Timing Question

    I have a running thread on here for my 1994 70hp rebuild (linked). In it I am all the way to to setting the timing, almost ready to crank up for the first time. I set the WOT cranking timing to 32 deg easy enough. However, when I backed the throttle back down to idle and rechecked it I was...

    Break In Procedure for Fresh Rebuild?

    Hey guys, I posted this question in the my rebuild thread over on the Force page but I thought it would be better to ask here. I am basically complete with the rebuild of my 1994 Force 70hp. All I have left to do is set the cranking WOT timing and then I can start it up for the first time. What...

    Finally pulled my head..top cylinder ate a ring

    And will this Loctite 518 Gasket Maker suffice for dressing the surface? It's what came with my rebuild kit (along with the spaghetti seal I don't need). A little research seems to tell me it is the right stuff. And would it need to be applied to both halves?

    Thanks. I forgot to include this picture I took this morning of piston side face.

    Need Some Basic Hour Meter Recs

    I'm supposed to be getting my powerhead back from the machine shop Monday and can start rebuilding it. My boat never had an hour meter and I would like to get one to help me keep track of the break in as well as track the total hours on the rebuild. Most of the simple digital ones on Amazon run...

    Evinrude Lark: Clymer or Solec Manual?

    My dad has an old 35hp Evinrude Lark. I believe it is a "Golden Jubilee" edition which would mean it is a 1959 model (right?). It has sat unused for about 9-10 years but it ran really great at times back in the late 90's and early 2000's. It just quit getting used because the old tri-hull it was...

    Powerhead Rebuild Kits

    Thanks. I got a hold of powerheadkit.com earlier and their current price on the kit for my motor is $475 + $25 shipping. It also comes with WSM pistons but it doesn't have the connecting rod bearing cages nor nor the two inner crankshaft bearings like the Ebay one does. Interesting dilema. Here...

    Powerhead Rebuild Kits

    I'm in the process of rebuilding my 1994 Force 70hp. I have an active thread on it on the Force/Chrysler subforum. I got the official word from the machine shop that I will need 0.020" oversized pistons/rings. So what are the best sites for getting the powerhead rebuild kits? I want a quality...

    Finally pulled my head..top cylinder ate a ring

    Luckily I was able to pick up the correct socket for the connecting rod screws Saturday night at Lowes. Yesterday afternoon I was also able to finally complete the teardown. Here are some pics of the piston from the bad cylinder. There was only one small piece of the top ring left...maybe 1/8 of...

    Finally pulled my head..top cylinder ate a ring

    Ok, I finally have somewhat of an update. I was able to pull the flywheel today after work, and with very little hassle too. The flywheel, magnets, and key all looked good. However, to me, the stator and trigger both looked not so good. The trigger has a visible crack in it and the stator...

    Finally pulled my head..top cylinder ate a ring

    This is the only shot I have with me of one of the good pistons. I believe the lettering on the middle left says "B4" whatever that means. It also looks like that may be a "1" at the 10 o'clock position but to my untrained eye it also looks like it just may be some carbon lol. Are there any...

    Finally pulled my head..top cylinder ate a ring

    Let me get the background info out of the way from the start. My motor is a 1994 70HP Force. I have owned it for the past 5 or 6 years and honestly, it never really ran good. I have dealt with a surging problem at speed which I initially was locked in on having to be an ignition problem. Who...

    Powerhead swap between different sized outboards?

    Particularly on the makes that are 30hp and under, on model groups that share identical part numbers for the lower unit, gearcase, and cowling, can the powerhead as well as fuel delivery and electrical systems be swapped? Seems like since you swap out everything that makes that model unit...

    Do my reeds look ok?

    I snapped a few pictures of the crankcase while I had the reeds out. It looked pretty good in there in terms of cleanliness. No noticeable carbon build up or set up fuel/oil mixture. The only carbon I even noticed was on the bottom center portion of the pistons. What I did notice is that in...

    Do my reeds look ok?

    I have a 1994 70HP Force. I cleaned the carb yesterday and replaced the fuel hose and inline filter. While I had the carb off I pulled the intake manifold off and the reed assembly to inspect them. The reed plates looked fine. There was no chipping or breaks and the plates laid flat. I held it...

    Installed new Tach but Doesn't Work

    So I finally bought a new Faria tach to replace the old one that hasn't worked the entire time I have owned the boat. Getting a new tach was a pretty big deal as my 1994 70HP Force has never run right and I am committing myself to fixing it this spring/summer. Anyways, I set the tach to the 12...
