    Default Sanger SJ question????

    Went CL for a poker run this weekend (first time, great time!!) Went to launch the boat friday morn and as always I ran it on the trailer for a few seconds (in the water). OH.... poop. there was water dribbling in where the pump is bolted to the transom, the dribble turned to a major leak when I gave it some RPMs. Boat out of the water. For those of you familiar with a Super jet, I tightened the 7/16 bolts that run trough the actual transom itself.... no improvement. Boat out of the water. I then went after the 3/4 bolts that are directly into the pump housing, they all tightened 1/2 to 3/4 of a turn. This cut the leak by 90% or so, even under a load. Way more than enough for a set of 500 and 750 gph bilge pumps. I ran all weekend with the pumps runing a little more than normal but not so much to be alarmed. Any ideas???? The boat hasnt been wet since the end of last August, Seal dried up?? Solutions (on a budget)??

    Some technical stuff 1980 Sanger Superjet, 464 BBC, 12JG-A, Place diverter

    Second question... I've had a Jet for 13 years, all my previous had TT exhaust. This one is OT and WAY more stout than my previous two boats. I ran this boat 14 days last year, never with the baffles in. It ripped (for me.... for now) 78 on two GPSs. Question... On the recomendation from a local I'm friends, with I put the baffles in so as not to have to meet any new LEOs. My impresive hole shot (for me anyways) was GONE. Top end took a while but got there. Not the boat I had last year, no mechanical changes cept for the baffles, are they the suspect??

    Thanks for reading and hopefully, thanks for your incitefull answers, Brian.

    From what you've said about the water leak under power and the 3/4" bolts tightening that much, I'd make sure I didn't have a blown bowl Gasket.

    I'll second that (blown or dehydrated bowl gasket!)

    The Bowl acually bolts to the suction with a paper gasket in between, the unique Sanger Transom adaptor ring slides over the bowl and seals the exterior of the bowl to the lake water Tom

    It is not a hard job at all, just take off the steering, pd if you have one, remove the bolts for the "sanger" ring, unblot the bowl and replace seals and put back together.
