Good idea, just have a dremel handy to cut/grind the threads sticking in the intake.

That would work too. I would just press-fit it though.

To answer other question, I believe all late-80's SB50 intakes are the same, but not sure on any year-to-year changes.

old thread revival woot woot! haha

I just took my Spree out of mothballs and am looking for some more go factor. I thought this mod would be a good one, but has anyone actually done it? Last 2 stroke I hot rodded was this.

Thats a BAMF merc stacker you have, I got a twin from the 50s im working on, d*** carb is all plugged up. This a good first mod, but be aware the sotck one can be filled out for similar effects.

Yeah, That is a Mercury TIIX (Twister IIX) 100 CID inline 6 making about 230 horsepower. I like to keep the stock plastics but make the motor different and parts swaps are easier than grinding, screw it up and have to weld it or get another one. I do have a tendency to over grind thing.

You may need to weld some buoyancy floats to the frame

It weighs just over 220 pounds, about 80 pounds less that the stock Merc 90 to 150 hp motor.
