okay guys and maybe some girls i am 31 yr's old and love high perf. boats , what in the hell is a gear box or transmission for a boat i noticed bigger /faster boats have them but i have never seen one or read extensively about one . dumb question but can you shift them ? or is it all automatic and how do they work just wondering .

FYI i am not in the correct tax bracket to own anything with a transmission lol

Beak Boater

Boats run transmissions because the drives they run dont shift. All the shifting is done in the trans. #6 drives, some older TRS drives dont have the ability to shift in the drive like a Bravo style or a Alpha. They are just F-N-R.

okay i gotcha are these transmissions just simple small versions of a manual car trans ?

Brad Zastrow

A transmission boat has a much beefier drive. Shiftable drives are more likely to break ie: Bravos. The Mercury performance drives such as the TRS, #3, #4, #5, #6, NXT1 and the new Number 8 all require a transmission. There are many transmissions made and most performance style are based on the Borg Warner "Velvet Drive". Hydraulics will activate forward or reverse clutch plate clusters.

way cool thanks for the diagram makes sense now , do arneson surface drives have a trans

Brad Zastrow

Arnesons, V-Drives, BPM, Konrads all use a transmission.
It would be a shorter list of drives that do not use a transmission.
