The AV plate of my 175 optimax now is 2.5" above the down off hull. At speed it was fully submerged in the water (2-3" off water over the AV plate). I have a problem with purpoising with alluminium black max 14.25X21 in turns/. I have to trim down before turns . How can I serve this problem? I want to by sst prop for beter top end performance and to avoid purpoising in turns. What kind off sst prop is beter to by in my case? May be i must by 4 blade prop and raise motor higher? I dont want to lose top speed. Beter to increase a lot.
p.s Sorry for my bad English.
