I-Boat friends,
The compression on one of the cylinders was 20 points below and someone said if I do the following
, this will help in I am trying to get a good gauge on my motor.
What do you guys think of the steps below:
1. Get a one or one and a half gallon gas tank, mix a gallon of gas 50:1 with 2 stroke oil, add to that mix a can of sea foam.
2. Remove the fuel line from your fuel tank and stick it into this fuel mixture, pump up the primer, add water and stir.
3. Run it at a fast idle 1500 - 2000 for 15 - 20 minutes, shut it off and let it soak an hour. Repeat, a couple of times.
4. Reconnect the fuel line to the original tank, fire it and warm it up.
5. Take it to the river, or lake, warm it up, the run it til it clears up good and no more excessive smoke.
6. Take it home and retest compression.
The sea foam will soften and wash out carbon accumulation in the ring grooves, freeing up the rings, often raising compression.
The gunk washed out is going to burn, smoke, and can take a while to clear out once your launch the boat and run it, don't baby it, hammer it to get it on plane then pull back just a little. You don't need to run it all afternoon WOT throttle, but 3/4 or a little more, 4800 - 5200, work it hard enough to clear it out fully.
Take along a spare set of spark plugs, often the gunk can foul a set before you ever get it wound up.
I am willing to try this, is there anything else I should know prior to doing this?
Thanks for the help,
RJ
