Offshoreonly.com - Upper gears: #3,#3A,#4 drives

Attention: All owners of Mercury Racing #3, #3A, #4, and #5 SSM drives. As you well know Mercury has decided to no longer make available any gears, shafts etc. for these drives. GK Systems Inc. has obtained permission, from Mercury Marine, to use the original blueprints and OEM manufactures of these pieces and will have available new, near net forged straight cut splined 1.31:1 upper gear sets.

Two different sets are now in production. 1 set will service the #3A and #5 drives. It is exactly the same set as the one that was discontinued by Mercury #43-818823A1. The other set, which was NEVER available from Mercury will have a near net forged straight cut splined gear and a "shaft" that will work in #3 and #4 drives. Polygoning for #4's will be available and will be extra.

Pricing on these sets was $2968.57 (retail) when they were available through Mercury. Pre-production discounts are available with a 10-12 week delivery time. Builder and multiple discounts also.

Think ahead: Keep your drives. You DON'T have to switch to another drive. Other ratios may become available if demand exists. For now GK is only going to have available the 1.31:1 ratio upper gear set and the next set that will be produced will be the lower gear sets in a 1.125:1 ratio.

PLEASE NOTE: These gear sets are made in the USA by the same company that made them for Mercury Racing using the Mercury blueprints. They are NOT made overseas!

Also GK has new propshafts for LH and RH #3A and #5 drives and can supply new "big-shaft" propshafts for #4 and #3 drives.

Please pass the word on to anyone that has a boat with these drives.
