Two more back of the boat questions:

1. Where is the bilge supposed to be located? Mine is in front of the engine.
2. Where is the blower normally located?

Thanks!

1 on my 81 the bilge pump is under the crank pulley
2 the blower is under the rear deck above the gas tank held into place by a rubber U

Another post was talking about blowing in from the front intake to get more cold air to the engine when running providing more power, Just like the cold air intake on my car....

Because I am moving the blower anyway, What do you think is better, Blowing fresh air in from the front or sucking the fumes out from the back.

Blowing fresh air in won't necessarily get rid of the fumes in the bilge; the priority should be to exhaust the stale air first. As that air is pulled out fresh air is pulled in. It would be interesting to see what, if anything, would happen to engine performance if you could lower the intake air temp any significant amount.

Would it make sense to have both an exhaust fan and an intake fan? How about two exhaust fans? Interesting concept. My gut feeling is that it wouldn't make an appreciable difference.

I agree with Rita, to have any appreciable difference you would need to intercool the air coming in to the intake (if you figure out how to do that in a MC let me know!!) However the push pull method of having two fans would not be a bad idea if the cost of the fans was not out of reach.

I am finally back at it after a two month break for knee surgery.

Working on the back end, Reinforced the transom, remounted the swim platform, New speedo lines and pickups, Gas tank emptied and cleaned, new flanges welded on, New rear exhaust lines, New blower,

Question on the steering head; I recieved some graphite packing from skidim, but it seems too small, when placed in the nut, there is a 1/16th inch gap between the packing and the steering shaft. Am I supposed to compress it until it squishes wide enough? or ? Also, how many rings should I use? I have two in the nut currently.

barefootjoe,
Did you leave the stabilizer tubes in? I had a leak in one of mine, so I bypassed it. Works just fine without it. Needle doesn't bounce much at all.

replaced one side, covered ends of other side with marine sylicone sealent by 3m, becomes rock hard after 7 days. Same stuff I used to help lock the swim platform, in addition to the bolts. Anny suggestions on the steering packing?

On the SKIDIM site they call for three wraps. Sounds like you might be using the wrong size. I believe there are two sizes. Which size did you get?
