Looking to rebuild my Rum Runner to be a one of a kind and contemplating what it would take to run triple 300XS. Stainless marine makes a bracket or will customize one for the application. What else do I need to think about before chasing this dream or throwing it out the window.

Thanks for in advance for your advice.

Check out pricing for a triple install on steering, I have IMCO for my twin 300X's. What speeds are you looking to obtain ? Twins on my MAGNUM SEDAN put me at 78 GPS. "HIGH LIFE"

Would like to get into the 90's. Also want the reliability for longer runs. I am on the east coast and like the idea of hitting the keys and The Bahamas on good days. Having some redundancy would make crossings a lot less stressful.

get a hold of Jimmy. James gang!

He has tripples on his 31 spirit. They had to do all kinds of strengthening to the transome and he has lots of pictures of what they did to it.

Basically a huge micro lam beam added in hoizatally.

(2 ) 300XS on that boat would probably run in the 90's imo

but it wont be one of a kind because one is being built AS WE SPEAK.

Thanks for the response. My plans were to redo the transom so that's in my thought process. Will definitely reach out to James G. Seen lots of pics and vid of his Spirit on the water.

Definitely interested in a one off. I posted on S&F for thoughts on verado 350sci. With the weight gain on the verado would definitely stick with twins if that becomes the route.

Yeah that boat is going to be AZZ heavy for sure. My boat with twin 200 mercs was heavy in the rear IMO and my 31 is a little bit but much better.

Theres a 34 down in FLA with twin OB's for sale right now?

I know your lookking for light weight and high MPH.


That hull is going to be a handful with tripple 300x's and thier torque I can tell you that much

I saw you post on S&F today.

what's the weight on the merc 200 compared to the 300xs. I thought it was 485lbs for the 200, 300xs is 505. Plus the stainless marine bracket adds positive buoyancy.

Comparing the verado, adding twins on that hull is 300lbs over the current setup and a net of 300hp more over the current 400, total engine weight 1330. Trips would be an additional 180lbs over that at 1550lbs and an additional 200 hp gain.

So:
2-Verado - 1350lbs - 700hp
3-300xs - 1550 - 900hp

I think the trips might be lofty and overkill. Won't rule it out.

btw, where's the 34 listed?

Bob posted on here that he was getting 88 with 2.5L 285 mercs. 20" shafts on a 22" bracket. I'm sure with 2x300x you'll get 90. More if they are built to like 335.

I really want to check out your boat when I get back. I plan on drive to get mine on the 28. As long as the owner meets with the surveyer and it goes well. Which it should.

tripples on a 26 will be a waste of time....300xs,s are very heavy but thats not the end of the story....add steering plates, tiebars and pistons (rougly 100lbs), 3 oil tanks (rougly another 100lbs), 3 batteries (rougly 50lbs each), a setback bracket (roughly 200lbs), props fuel and oil in the motors (the advertised weight is DRY so add another 20lbs to each motor) and after all you are going to wind up with 2000+lbs hanging way off the back of a 26ft boat....

get yourself a nice used pair of 300x motors which made about 320 to the prop and call it a day...you will probably have a high 80s if not 90 MPH boat....you want something uniqu then put a crazy paint job on it or something....
