    Nominal cylinder compression in 9.9hp

    Anything above 100/100 is great! Actually over 90 on each cylinder will do. Bring close is more important than the actual number. That gauge will work but I’d get one of the ones from auto parts store. I’ve had better luck.

    difficulty with cold starts-E10EESC

    last 2 days I've been able to cold start motor on first pull. I twisted the cam roller follow in about 1/4 turn and was able to turn the low speed idle screw out about 1 full turn (2 and 1/8 now) I think this increased rpm on start and allowed more fuel to be used while starting causing motor to...

    Attempting to repair slow leaks in 12’ aluminum

    I redid an old aluminum boat last winter. I recommend drill out and replacing the failing rivets. This is the simplest and most effective way to repair that. As far as the seams go I used a product called g flex on may rivets and seams both. Worked great. I can’t praise that stuff enough. You...

    difficulty with cold starts-E10EESC

    Yes bulb gets hard and stays hard. Yes I am advancing throttle to neutral stop. My tach shows rpm at 2800 when I start motor. I sprayed starting fluid on both side of manifold to see if leak. No increase in speed.

    difficulty with cold starts-E10EESC

    I have the cam roller follower just touching the dash mark on the stator plate as the butterfly in the carb starts to open. I believe the throttle timing is adjusted correctly. I hooked up a tach to help me. Motor will idle at 900 rpm and I can get it around 2800 rpm when the trottle is advanced...

    difficulty with cold starts-E10EESC

    I did exactly as recommended above: pulled out choke, pulled rope, pushed in choke pulled rope again. Fired right up on second pull when cold for first start of this fishing trip. However throughout the day I shut off the outboard while using trolling motor and for restarts to move positions on...

    difficulty with cold starts-E10EESC

    I will disconnect kill switch and test start motor. Yes. Strong blue spark in both leads that jumps a gap of 7/16" with ease.

    This outboard is a tiller handle motor, and I am advancing the throttle as far as I can to the neutral stop.

    difficulty with cold starts-E10EESC

    Hello and good morning, I have a new to me motor that I would like insight on how to repair. The motor I have is an Evinrude 9.9, and I believe a 1990 model. I am having trouble starting motor at the beginning of a fishing trip. The motor will sound like it wants to start with the choke...
