I picked up a 98 42 fountain two months back. It was a trip boat that is being converted to stagger twin setup. I picked up a set of ssm 4's with net forged straight cut upper gears that are fresh. Motors are going to be 515 ci with either 10-71's or 12-71's. That should put them at 800-900 hp. Mild thunder has been helping me with choosing parts that will get me to my goals. I'm going to build the motors but most likely going to take them up to Joe and mike to dyno them. The boat is going up to glass dave in a few weeks for him to work his magic on. As of right now we are going to do a 19.5" on center and a prop shaft height of either 3/4-1 inch above the bottom. I plan on running 5 blades so that should work nicely.

. I got it stripped and ready for glass dave.

Cool project. Where are you going to boat with her when it's done?

Lake Michigan/Erie, Cumberland. We will probably still boat alittle at Monroe.
We have wanted to boat in big water and hit up pib but we were always scared with my 31 and the weak drives/ supercharged engine combo. Really excited now that the project is underway.

That should rock when done.. So looks like someone pulled the center engine & has been running her as a side by side , any details on how that set up worked?

I don't have any details on the previous conversion. I don't think they ever ran it.

Little update. Sold my motors and decided to buy rob's scorpion racing engines. Once I get those down here I'm
Going to sell off the 250 blowers and carbs and then change to the larger 10/71's. With chillers and 8-10lbs that should put them at a solid 900 plus hp. Does anyone want to guess on speeds?

110 to 115 when dialed in.
