Thanks ibhawgman, cart7 and ben,
I'm going to do the filter and primer bulb tonight--I changed the plugs already.
If that doesn't fix it then I'll get the compression check done and have the coils and powerpack looked at. I checked the prop last night and it is a 25 pitch Tempest with no vent plugs in it.
I've had the boat up to 5400 rpm doing 70 and I backed off of it. My Astro fish and ski with it's 135 Merc was a just a little bit slower than this one.....haha
I've only had the boat for a month or so and have had it on the water 3 times--problem got worse each time, especiall this last time.
Thanks again for all the replys,
Smib
