will a hpdi lower unit fit a 02 225 3.1 liter vmax and what mods needed thanks Randy

[shortcast]

Yes it will fit, all you need is a stud and nut kit to replace the bolts that hold the lower unit on. And you may need a pitch change on your prop just depends on your rpm's. I just ordered the kit from HydroTec. They will help you with advice and parts.

Looks like I'm late as usual. I posted on the yamaha board.

Will the series II lower also fit a 150vmax? Is it worth a few mph?

[21XDC]

No... The 3.1 and 3.3L will swap... Not the 2.6L.

If your currently spinning a merc prop on the efi lu. You will need a different thrust washer than what you're using now.

i need a diffrent thrust washer for the prop ????? and what kind

[21XDC]

Only if it rubs the lower unit or zerk fitting. I have run many of Merc props with flo-torq and rubber pressed in hubs. You should run the Merc/yamaha flo-torq hub kit that comes with a thicker thrust washer on the props that have a flo-torq hub.

Mike, that's the part # for the thrust washer on a flo-torque hub to Yam PDI?

If so, HT is currently out of stock. Waiting for it to come in.

Thats the whole kit. The washer by itself is almost the same money. If you really need one quickly>> http://www.boats.net/parts/det....html

Isn't that a load! Nearly the same price as the bearing alone. I believe I'll buy that on line. Mike that is the bearing that will fit the HPDI right?

[21XDC]

It's the one I use and I have an HPDI LU... I also use this. http://www.boatfix.com/bykeywo...earch
