Can I chime in? I had a 502 Mag EFI in my last boat. Went through three sets of manifolds and risers. Stock Merc stuff was crap. I have run HO's for the past three seasons with no poblems. Knock on wood!! Start better, idle better, eccelerate better, run better.......overall better IMHO.

Anyhow it would be a nice boat but the resale on it will not be a good as the twin step 35. The cockpit room differance and engine room access differance is very much greater with the 35 twin step plus the 35 twin step with 525's will see your goal of 90mph.
Thanks for the "heads up" I forgot the Ex is a single step...I have looked at so many boats this summer I can't keep it all straight.

I saw a good deal on an Ex with 496's and was thinkin about maybe going for it now in the winter.....adding blowers later..but it seems like that's not the way to go. Durability would eventually become an issue I think.

I've heard this before and always figured it was the fresh water cooling that eliminated the 502 Mag corrosion problems.

Tommy from Chief Engines always tells me: "There's no replacement for displacement."
He wouldn't even touch a 396 Chevelle engine for me 'cause it was too little! (Elitist little bas####!)

More cubes equal more torque...boats need torque...502 has more cubes.

Maybe mortgage the house and get Triple 525's on a 42X (I think Lake Cumberland has it on hold for me.) Buy this and I can finally get free of being called a knob!

I too had 502's and replaced them with 496 HO's. I much prefer the HO's. They run so much smoother,no oil useage or corrosion problems. Better fuel economy. Performance is slighlty better than the 502's. It was the best decision I ever made. I learned with the 502's to get a diagnostic tool and it was one of the first things I did after motor installation. Carry it with me on any long trips.
