Hey Don its Lil Red again. Model # 0G644050 I have one of the frankenstein motors that you love so much.I sent you pics a while ago and your reply was:
From what I can tell, it appears that you have a later-style EFI 200 block assembly, on which all the earlier electronics and fuel system were installed (from the original engine).
1. I have been reading a couple different places about what grade of fuel to use in summer/winter so I was wondering what type for my 200 efi?
I have been running 93 octane w/ ethanol, and always quicksilver premium plus with a Don cocktail.
2. Can I do the 3 liter cowl mod to my 200 efi? will it help at all? or will it hurt? Also can I or should I do the clam shell under neath?
Is there any other easy/ cheaper mods I should look at that will help the performance/extend the life of my motor.
Thanks for the replies and yes I know its a little ole 2.5 and this is the 3.0 board but Don has helped me since I got this boat and this board seems alot more active/informative.Thanks in advance
