I have 2 1996 SPI's, both are in great condition expect for the OEM 2 piece wear rings just came apart, looks like the black seperated from the fiberglass portion. I bought 2 new SBT 1 piece rings and installed them but I did not use a neoprean seal around the pump, just siliconed the whole housing where it mates to the hull, waited a week then went for a test ride... Horrible cavitations on both most of the time, they will still get on plane but any kind of slam acceleration or spin out is denied.
I recently just read the wear ring how-to by Dr. Honda and im now curious if you don't silicone at all and just use the seal? What else could cause the caviation and lack of pickup with a brand new setup besides it sucking air, im guessing?
Also I have to take the ride plate off of one in order to break the one pump loose where the previous owner had so much silicone on them that I couldnt get the pump off. One thing to note is they both had neoprean seals on them before and tons of silicone and they ran like a charm...
