i was thinking mine was running a little slow, i get @ 30-32 with just myself, low feul tank. i thought my etec could do better. i’m looking into an after market prop, motor position etc.
You should be doing better than that with the E tech on back. My Yamaha has better top end spend than the E tech did but only by 1mph or so.
I have a old E tech prop in the garage still. It needs repair but other than that it should be good to go. If someone wants it let me know. There is some oil in there to.
i may be wrong but…. i think the only difference between a 75 and 90 is a computer chip. may be fuel injected models only not for carb motors but i know some1 who did that and got major power boost but for a spendy price of about 1k. b something fun to find out~!
