    Question Sealant and Silicone Help!?

    Hey,

    In the process of reinstalling my temperature sensor on top of the engine and I would like to know what kind of sealant I have to use on the threads?

    Also, what type of silicone should I use on the sponsons bolts?

    Finally, what type of sealant should I use in conjunction with the neoprene seal on the turbine seal to the hull?

    Thanks

    --- Loctite 518 Anerobic Sealent (Red Goop NOT Red Thread Lock) on the Temp Sensor threads

    --- Ultra Black "Silicone" (NAPA Auto) on the Sponson Bolts with a Bead around the Sponson Backs and
    Flat Backing Washer inside the Hull

    --- No Sealent on the Neoprene Seal unless the Jet Pump has the (3) Hull
    Penetrating (2-Siphon Tube and (1) H.P. Water IN) tubes connected to the Jet Pump,
    then put a Bead of Ultra Black Sealent around the holes in the Hull and around the
    (3) Tubes and torque the Jet Pump Bolts to Spec. and let cure 24 hours.

    The Neoprene Seal should Seal the Jet Pump perimeter fine if it's installed correctly.

    Jet Pumps // Hull Sealing methods are different depending on
    which year/model you have which you didn't mention.

    Wow! Nice!
    Thanks for the reply!

    The model I am fixing is a Sea Doo 1996 SP... And there is 3 tubes penetrating the hull so I should put ultra black only around these right?

    Thanks

    Around the Holes on the outside of the Jet Pump Well fibreglass
    where they penetrate and on the Tubes themselves at the BASE where they screw into the Jet Pump body.

    Ok Thanks!
    Just to be sure, I do not need to put a little gap of sealant around the seal? Because when I first removed it, it seems like there was a sealant around everywhere even with the neoprene seal... Was like that from factory! :S

    Shouldn't need it if the Neoprene Seal is doing it's job.
    Be sure to scrape/wire brush *all* the old seal/sealent off down to
    bare black plastic before applying the new Neo. Seal.

    On the temp sensor..Allot of those are self sealing threads so nothing is needed.
