Stephen,
I've run this pump for years, and I'm curious, where did you find one to fit
a Tiger. I had to make mine from SVO parts, including pulling the old
impeller, changing the seal, and pressing the new impeller on to the shaft.
A lot of effort, but I consider it worth it to reduce the cavitation common
to straight blade pumps. This is particularly true with 3.54 and up gears.
It frequently takes a lot of effort to pin down why your Tiger runs so hot.
You must be sure that you have covered all of the basics to assure that your
system is operating at full efficiency. You also have to be sure that you
don't have problems like combustion leakage into the cooling system. The
problems are frequently overlapping, and this makes them hard to pin down.
We, on the net, may be able to help you if you can be specific, and tell us
what youv'e done to date.
Because of the electric fuel pump, vapor locking is not a common problem.
You will have to define your terms so that we can offer suggestions.
