    I'd start with new plugs and a new lead for the top cylinder db.

    Re: Interesting outboard problem/occurence

    Thought engine problem was fixed, $500 new plugs service tune top seals on gearbox and thought good to go. Mechanic told me was lots of water in trap when he checked. Took boat out today for 1 hour and once again when running at 4500/5000 revs motor likes revs and power. Very frustrating, should I drain all fuel from u/f tank and refueling with conditioner, run motor at high revs with syd tank?. Can the coils play up when they heat up I'm wondering if one cylinder is not firing when gets hot.

    db, don't know about outboards, but when I rode bikes yes, the coils could start to play up once hot.
    Invariably, within a short period of time, they subsequently died. Same with the old Holdens we had too, from memory.....
    Were the leads and plug caps replaced when the plugs were changed?
    Good luck with it.
