Not that it matters, but anybody have some fuel burn numbers for an 88 special. Mine is on an older McKee craft 17 Offshore trihull. 1480 pound hull, probably holding a little water so figure 2400 pounds with motor,fuel and two average guys on board. Like I said its new to me so i have not run it yet to try and figure it out. Just wondering.

Holding water ???? Is it leaking or water soaked flotation foam.
Rule of thumb is 10% of HP at WOT per hour. Therefore a little under 9 gallons per hour at WOT

Dont know yet about holding water. Dont really think so just that boats seem to get heavier with age. havent run it yet. Thanks for the info.

The plugs in it now are NKG R BR8HS 10. Saw that they should be BR7HS gapped.030. Is that right. Also somebody said use Champion instead.

Agree 100% Use the correct champion spark plugs.
They only get heavier if there is an issue with them.

All closed cell foam eventually breaks down; if water is allowed to reach it and saturate the broken cells, it is nearly impossible to remove the water without removing the foam.

U.S. Composite has a FAQ that basically covers most types of foam used in marine applications: http://www.uscomposites.com/faq_foam.html#14

Agree 100%. As I said only if there is an issue. The issue potentially being water laden foam.
