I know that 3 2.5' s will throw off the weight of the boat it might be to stern heavy but has it been done. I would like to put 3 300x's but that will be to heavy for sure. What type of speeds do you think you can run with 3 2.5's stock? And how about 2.5's modified like Charlie's? I would think this set up will not take jack plates as it will push the weight further back. Would the boat be unsafe to drive to much speed for a 28?

it has been done,also a 32 with 4 300 called scorpion and paul whittier did old 32 with quads

It HAS NOT BEEN DONE. The Sting has 4 2.5,s so did Whittier. There are a few triple 28's but not all 2.5's. I think it would be a waste of time and money to do 300's and it probably wouldn't handle well at all.

Ryan with triple stock 2.5's what do you estimate that the boat will run? 125ish more or less. Now what do you think it will run with 3 2.5's modified by Diamond? 135ish more or less. Aren't the 2.5's problematic?

Alex where are you boating at? 3 2.5 set up right will run 130ish , 3 pumped motors maybe 140ish , but the boat is too small for that, do you have a death wish? My 24 doesn't go 100 and its fast enough. They only days a 28 will ever go that fast is if it mirror calm. Lets be realistic about htis, the is no need to go that fast in a PLEASURE boat thats 28 feet long. Fast YES, cool maybe, dangerous FOR SURE.

There is a triple engine 28' at LOTO. It was built for AB and now it is owned by someone else running around.

300's or 2.5's doesn't make any difference. Its too much ass weight for anything other than really calm water.

Three engine 32's or three engine any cat it not the best as the center engine gets beat to death.

My friend has a 24 Skater with twin 2.5's with a little work by Diamond and he has gone 122 on GPS. I would love to build a 32B but there are slow with outboards. You can go faster on a 28 than a 32 with one less engine. One engine less is one headache less. I dont know of any 32 with 3 outboards thats touch 125.

A well set up 32 classic with STRONG 2.5's should run close to 125. There were a few Pro Stock triples that were right at 120 with stock motors. Your buddies 24' is fast but only up to a 2 foot chop.

Isn't the 32B faster than the Classic? Also what should the classic run with 3 300x's? I know the the 300x's come in 20in but they sell a kit to convert them to 15in I think coverting them down to a 15in should give you a little more mph the CG should be better than having that big heavy head so high up? So a tripple 32 Classic is faster than a 32B? Thanks for a the info by the way.

I don't know how a 32' B runs, but I know that the classic can run those speeds. No one has done a B set up like a race boat, the class died befre the B came out. I think the B runs better with I/O than the classic. It is MUCH larger more like a 36.
