Piston
From '86 to around 2001 Suzuki made what they call a Super Six. I few different theories of why they did thisand what it means. The 150 Super Six which what is on my boat, they say is rated at closer to 200hp, back in the 80 the bass boat guys put a 150hp restriction on bass boat tournament class. So, Suzuki put two plugs per cylinder, slapped a 150 cowling on a 200 and spanked all the other boats out there. They also got in trouble from the NMMA. Other say it was to help in long periods of idling for trolling and such. Won't foul plugs... I tend to believe the first one. My boat runs pretty well. If nothing else it looks cool. It has regular dome type pistons as shown by the picture.

The 150 super six and 225's got the dual plugs due to the aggressive porting. Be careful rebuilding a 225 as it is a boron coated sleeve to handle the HP with small displacement design. Many will put steel sleeves in, but they do not hold up like the boron ones did. See if you can find a good block jug as that is a modular engine and you can replace the cylinders and pistons without pulling the powerhead. And have the injectors cleaned and flow tested by a reputeable shop as that is the #1 killer of EFI 2 strokes.

Boron
Yea I have heard that about Boron. I was going to look for a different block. But, as you can see from the pictures this motor already has .020 over pistons. It must already have been bored or sleeved. It looks like I dont have a choice but to sleeve it and not run it to hard. Is there one sleeve that is better than the next? Any suggestions?

Wolf my concern is weight...the 225 looks like another 20"er, too...if the smaller motor left you the typical 4-5" at the tranny, what's the heavier V6 gonna leave...did I miss somethin"...

V6
The 225 is a 25"er for sure. The 150 and the 225 are virtually the same block in fact they use the same crank. The 225 will be a little heavier because of the 25" shaft but it shouldn't make much of a difference. Does any one have any experience in raising the transom? Do they like the results???

All of the V-6 2 stroke SUZUKI's were 2.7L engines and weighed within a few pounds of each other, so weight won't be much more. A 20" ZUKE will weigh about 470 pounds, so it is a fairly light weight 225 but heavy 150.
