Alright I'm going to ask some dumb and controversial questions. How do we get more power from the 210?

Same hull as the 212x, right? Can you stick 1.8s in it? What would that require? Are the pumps the same? Engine mounts? How about squeezing more power out of the TR1s? Found one other thread on here discussing the Riva tuner but didn't hear specifically about the FSH.

Don't care too much about top speed, really looking for more ability to get on a plane with crew and ballast for wake boarding.

I haven’t had much luck yet, looking at Riva Tuner and impeller changes, but in all honesty my next boat will likely be bigger and an outboard in 5-6 years.

I don’t know I just really don’t know. I do believe that the 1.8 ths have a larger pump I’m pretty sure of that. I guess you could steal two Jetski’s with the 1.8 and supercharger in them and do the switch to keep the cost down. No one on here has put 1.8 in a FSH 21 yet that I know of no one on here has put 1.8 in a FSH 21 yet that I know of. To do it legally it’s probably $30,000.

Lemmon won't be worth the squeeze. Just get a new or different boat.

Interesting as I am considering going from IO/OB style to jet. Can you elaborate on why youre going back to OB? Thanks.

Going back to an OB boat is due to my desire to have offshore capability in a 24'-26' (or bigger) boat. You are pretty much limited to an OB in that size and description, though I have seen a few old inboard builds like that.

@Dixie Highway If you go big enough then you can just keep your FSH on the new boats back deck with a hoist for an inshore runabout. :) Seen this on a few large yachts out my way, ridiculous.

That will depend on my luck in the lottery I suppose. FSH would make a FANTASTIC yacht tender....

Yup. Personally I feel 23ft and above twin engines are necessary especially if running offshore.

Check out Sea Pro w Zuke outboards.

maybe you could repitch your impellers ?? maybe the lucky 13 cones ??

those might give you more torque ?

Swatski had an AR190 that he did some impeller/cone work on, I think he used the Riva tuner on his 1.8l also, you'd have to search some of his old posts to confirm,
