x10:big grin Its a little plastic worm gear that your trusting not to break!! The older the pre 2000 the better not to have the oil injection. Since 95 was the first Im surprised its still in there thats a long time!! Mines a 96 was stock until l 08 or so when I took it out.Theres a reason even Merc, sells the block off plate for when you remove it.:big grin 10 bucks some dep 6 some hoses and tanks your done. Buy a couple little premix plastic contains with screw on lides for 5 bucks each and stow them in the boat. i actually find premixing 40-1 easer than before. Filling that stupid on board tank without spilling was a PITA.
Theres a detailed with pics instruction on hear and Scream and fly. I think its just under {oil injection removal}? Takes an hour to find and unscrew the few things to do if never done anything like that before. The security of knowing no matter what your getting 40-1 is priceless.
