Propheight twin Promax 300??
Hi!
I will mount two PM 300's on my Phantom 25.
Merc Hi Performance reccommend to rise the engine 6 inches with Torquemaster lowerunits and 7,5 inches with Sportmaster lowerunits. Top speed will be approx. 86-88 mph.
The Phantom 25 weight is approx. 850 kilos without engines and driver. With engines approx. 1.150 kilos plus driver and gas.
The engines will be mounted direct to the transom due to the total weight aft.
With one engine the propheight is 2 - 2,5 inches below the bottom with 7,5 inches setback (CMC powerlift and spacers). The boat is bowheavy and need positive trim to run fast. Current top speed is 76-78 mph at 6.100 rms.
Any ideas and suggestions?
