81 merc. 225 black max question

[Bigshrimpin]

Here is a picture of a newer 25" Mercury. 1990/91 and later had this longer 25" midsection. If you can find a donor motor (check local merc dealers) . . . you can bolt up your powerhead to the mid-section . . . it'll give it a newer look too Just make sure that the T+T works and that the sterring arm and bottom yoke isn't rusted to hell. You can put your spacer on this mid and go 30" with a 5" extension.

Bigshrimpin .. Most likely more of a PIA than I anticipated, thanks for the info. Just going to have to learn to resist pushing the throttles all the way forward for a few years until I can upgrade to something newer in the way of power.

Those old 1981 v225 are tough engines . . . they can take a LOT of abuse. I wouldn't hold back running them WOT . . . just make sure the idle stabilizer/spark advance modules are gone. The stock wh-20 carbs on that motor will drink some fuel, but the sound from those engines is awesome . . . kind of like a nest of angry hornets when turned above 6,ooorpm.

I ran one for a few years with wh-22's carbs . . . burn was only 10/11 gph @ 4000rpm and 20/21 gph WOT.

wh-22 carbs? where can I get them? motors run great but they're a bit thirsty.
