Friend of mine claims running 90 ish with a 2005 42 fountain staggered twin 525...

How's this boat running compared to my friend's? Pros and cons?

How do those sit in the water?

Thank you for being able to spell "triple".

TBH your friends numbers sound a little high. I was under the impression real world numbers on stag 525 42 were closer to 85-87. Talking peanuts here but still a difference. I would think a triple 500hp should be able to outrun a twin 525 boat. I know the stag helps with a higher ex. Both are stepped hulls so speed is negligible there. The real big step 98-99 boat may have been a few ticks faster in the 80range. From my understanding the latest bottom which your friend has is designed for better handling and stability in the 100s. The big step will get there but the later bottom was better once there.

It's in Vermont but only has fresh water hours?

A staggered 42 with 525's will run mid-to-high 80's unless it's nearly empty on fuel and the conditions have to be perfect, stars aligned, etc... That triple 42 will probably run around the same or maybe a few mph more but it's not a 100 mph boat..

Lake champlain area so yes fresh water

That was also my thought... No real speed advantage so why have 3 engines for same speed as 2? Except for paying a 99 cheaper than a lets say an 05 model...
Still wish i had one!

The triple will be easier on drives. This is a very clean well maintained boat, I've known Doug for a long time. He's one of those guy's if something is not right it will drive him nuts till it's fixed.

you seem to know the boat! not written in add but do you remember if it has shore power. ac and heat, pump out toilet! gen a plus if it has it
