Ship Shape TV

Guys-

I saw an episode of Ship Shape where John is putting a new Mercury (I think) on his SeaBird center console. He needed a 25" shaft for the bracket, but put on a 30" as he believed the higher level of the engine would make for a better ride and help to keep sensitive electronics just that much further away from the ocean spray.

Did anyone else se this episode and what do you think??? Sounded like it might be a good idea and the boat looked slick with the engine raised a few inches.

I caught half of that one but my son wanted to watch Tarzan [img]/images/graemlins/tongue.gif[/img] . I heard him say he wanted the engine higher to keep it more out of the water but I didn't hear the bracket was setup for a 25. If it was setup for a 25 and he put a 30" shaft on it, it's just gonna drag a lot more with more below the water line. It's not going to make a whack of difference to keeping the motor dry unless the bracket is mounted 5 inches higher - in fact, probably be wetter back there

You can go to www.shipshapetv.org and ask them your question about mercury motor.

I saw that show and if I was a bracket guy that’s the way I would go (AFTER) I talked to the engineering department of the Armstrong Bracket Co. to find out about the differences in the buoyancy of the bracket being mounted 5” higher on the transom. That point was never brought up on the show and has always bothered me. If they aren’t compensating for that extra 5” higher mounting then the bracket will not be buoyant enough to compensate for the weight of the engine.

Fellow-Ship, that's exactly what I was thinking! [img]/images/graemlins/smile.gif[/img] Use it the way it was designed or go custom!

I reread my post and I guess I wasn't very clear, I'm sorry! As I remember, the bracket was mounted as required on the boat without any modifications. The 30" shaft engine was mounted 5" higher on the bracket so that the lower unit rode at the correct depth.

That seems to make more sense! From the video shot upon complettion, the boat rode well despite the modification.

Hoop ...you going bracket ??

I agree with Fellowship.... I've talked to Stainless about this and naturally you can have it built how you want it .... and If not mistaken while talking with Don (Hermco) the Seamark bracket which is built for twins does give you the added height above the water line and tons of buoyancy (like 890? lbs) using this bracket allows you to mount a 30" single. Don’t forget on a bracket the motor gets mounted higher than it would on the transom anyway due to rate of rise of the water coming off the bottom and the setback of the bracket....

Hoop I missed your second post ....

look at my last sentence

I get ya Scott, I didn't realize that the Potter bracket was intended for twins. Makes sense tho!

Hoop ...He makes both ... a version for singles(25") and one for twins(30") ...the twin model is for a single 30" or twin 25" I personally like the 30" to get the motor up higher and to accommodate something like a big 4 stroke
