200 hpdi on a 18

[ScottM]

I Have a 25in. So i am think it should be fine. The 200 Hpdi weights less than a 150 Hpdi so why not go with more power.

ark,
Take a look at Yamaha's specs again. The 200hp HPDI with a 25" shaft will weigh the same as the 150 @ 475#. The weights quoted on their site are for the shortest shaft length available, and since the 200 comes in a 20" and 25" and the 150 only comes in a 25", you need to compare apples to apples.
