I have an 01 518vx with a 01 200 optimax. It has an 8in hydro plate and I'm currently running a 23p tempest, 61mph at 5700rpms, decent bow lift but doesnt feel all the way on pad aka no chine walk and my buddy riding beside me says about 1/3-1/4 of the boat is still in the water at WOT. I first bought the boat in december, borrowed my uncles 25p tempest and it ran 68mph at 5700rpms and was definitly all the way on pad. Gave my uncle his prop back, bought a 25p tempest on here, had it worked (1 blade was about 1/4inch off of the others) and polished. Now I cant get the bow off the water even with max trim, also I cant get RPMs above 5200-5300. It has 2 PVS plugs just like when it ran 68mph. The only difference is I put my gear in, which is not a whole lot compared to people Ive fished with. I ended up going back to the 23 for tournaments this spring. Any suggestions or can tackle have that much effect on performance??
