Awesome post guys!
Excellent stagger post MC ! Just to add a couple of notes, stagger's allow ya to run faster with less throttling in a chop as they don't unload the props as often ( easier on drives ) they also fly straighter when coming off of confused waves as they tend to unload together reducing the twist or roll as one unloads later. On the saddle tank front we were able to reduce the roll effect by keeping the tanks low and contoured to the hull bottom for the most capacity, they're under the diamond plate below and hold 75 gal each.
Awesome post guys!
WWon, HUGE thumbs up.
I agree about the weirdness of the backwards motors, but I've seen a bunch of em in old vee drive and straight IB drags. (usually no belts, no accessories). As with most unconventional installations, there are pros and cons.
I'll find pix.
I see London, I see France...
Will the big Sun be a full stagger of just a partial stager. I thought I read in another post that it was just going to be a partial stagger. You really don't get the full benefit with partial because the drive lives are still the same. Right?
Wow! Wicked one... that is one super sanitary engine compartment... I can see there was lots of planning in building that!... Good job!........
Wicked Won, Clean machine!
The new Sunsation will be partial staggered. I believe that is pretty much how most of the staggered setups are. My understanding is that takes the drives from about 3 feet off center to about 2 feet, so it moves the drives about a foot closer together.
Allright now you're just showing off. NKOriginally Posted by mcollinstn
BTW My engine room would look as clean as ww's too if I never went boating.
I know this is off the subject but I will add a few things.
Mcollinstn did a great job on describing the set-up the only thing is the motors face flywheel to flywheel, The power is taken from the flywheel. The system is automatically counter rotating when the motor is installed backwards.
I changed water pumps on nigels boat and it was not that bad. The serpentine belt is a pain but to re-install when the motor is warm but cold would have been a breeze.
The photos Reed showed were of the Fountain project with the #6 drives. We ran a very tight centers on that one. Nigel does not run the rear boxes, just straight into the WSD drives.
The distance between the flywheels is being reduced. It is now 15 inches. We redesigned the dropbox/FNR to shorten the distance. Most of the room was needed to clear the double cooler bellhousing. We are now making a purpose built housing to accomidate our dropbox system.
The whole set-up was put into a standard staggard engine bay. The motors in-line it now allows us to use the waisted space that the engines were using up. We are working on a purpose built boat to show off the entire set-up. The exhaust will merge just after the rear motor into two (one port one starboard) tail pipes at 6 inch dia. It should sound pretty mean.
The boat inside is about real estate. side by side (SBS) more room Aft cg and high cg. Saggard less room better high speed handling fore cg and lower not so great low speed. Wider centers (SBS) better control around the dock.
Weismann In-Line, the best of both worlds and then some.

I spoke to Pat once about coming down and looking at your stuff... but I can't ever seem to find the time and Costa Mesa is a little off my beaten path...
