Twin Promax 300's - how close?

[Toffen]

Hi!

I know I have been into this before, but pls help.

I have made some serious measurements, and I can get two Promax 300 on my Phantom 25 (its only 5,5 feet wide) if I mount them 21 - 21,5 inches senter to senter. This mean 1 - 1,5 inches between the cowlings. I can not wider due to the stringer system at the transom. Is this possible?

I also need to convert to 15 inches midsections, as the engines will be mounted direct on the transom. Is this possible to get hold of?

Its reccommended to rise the engine 6-8 inches with a twin installation according to Merc Hi Perf. Any ideas of propheight?

Wouldn't it be better to put the twin 300s on the Skater?

Or what happened to your Skater project?

Btw, I think Wayne Taylor sells shorter mid-sections for 3 liter Mercs.

Hi!

I have been waiting for a while now on the skater. Look better now. However, I am looking at adding a second PM 300 on the Phantom if the skater project fails. I still the skater will be up here during the summer.
