    250 Inline 6 Front Mount modification

    So I picked up the new rebuilt block over the weekend. First thing I noticed was the tab on the front of the motor on the starboard side was missing. I've heard of a few people making a bracket to fit in between the timing case cover and the oil filter. Anyone have any experience in this...

    MC-1/Alpha 1 Trim Issues

    I replaced the old pre-alpha housing on the transom with an Alpha-1 Gen 1 gimbal housing/transom plate last year. When I did, I had to use the Alpha 1 trim hoses (larger dia.) instead of the existing trim hose (smaller dia.) because my existing braided hoses would not mate to the housing due to...

    Re-wiring/battery relocation

    I'm thinking about re-wiring my boat. It's a 21' cuddy cabin I/O, with a fresh motor and outdrive. I want to relocate 1 of my batteries towards the bow, since it gets in the way next to the motor, and I'd liek to be able to remove the rear seats for added fishing room. I have a dual battery...

    Alpha 1 Gen 1 - Exhaust Bellow vs. Exhaust Tube

    I just replaced the u-joint bellows, intake, shift cable etc. When I purchased the kit, it came with an exhaust bellows, however I understand there is a newer style that is a tube. The new style is supposedly much easier to install as it only bolts to the gimbal and not the bell housing...

    I have a friend who just bought a Bravo 3x paired to a 6cyl turbo diesel. He hit something and took the boat out of the water. He had to take the drive off and send it to the insurance adjuster. When removing the drive, he had the boat in forward (he's used to the alpha's). He said he did...
