1999 150 efi Murcury

[THEFERMANATOR]

A 15 pitch prop in the MIRAGE line may be a better choice as that 99 150 will have the 1.86:1 lower unit in it. Expect WOT speeds around 40-43 like Reel said, but fuel burn numbers on that engine should be around 12GPH at 3800-4000 RPM's and 18-19 GPH at WOT if it is like my 95 150 EFI I had.

I've got an 97 150 EFI thats going to end up on the back of my V, plan to do a few mods to get it a little faster than 42

I thought 150's had a 2:1 gear ratio

2.0L's were the only V-6's with the 2:1 ratio, the 2.4L+ all had the 1.86:1 in them. A 99 150 EFI is going to be a 2.5L.

It is a 2.5.
