    1976 Mercruiser 233 (Ford 351w) carburetor issue

    Question for the brain trust. When I activate the the accelerator pump on the carb by hand it squirts fuel into the card but only on one side. The picture above shows fuel going in on the left (red arrow) but nothing on the right (green arrow). It should be both sides, right?

    MC-1 to Alpha Fitment Question

    My 1976 MC-1 drive (SN 4518534) gave up the ghost today. The drive shaft still turns and there was not burned rubber smell, so the coupler is okay. With engine running I shift forward, and the motor revs, but no prop movement. Same with reverse. With engine off and the shift lever in neutral...

    I have a I/O boat - 1976 23' chris craft lancer. It came from the factory without a swim platform, but it has a folding transom ladder so getting on the boat from the water is doable. I have been considering installing a wood swim platform but not sure I want to mess with the original style...
