    Alpha one gen one on gen 2 gimbal housing

    Never mind I figured it out, the shift shaft in the gimbal housing sits 1/2” lower in the gen 2. I could modify it but I will change the housing , I don’t feel like screwing around and finding out I’m wrong. Thank you for the info you saved me a headache

    4.3l electric fuel pump conversion

    Actually I started with a 3.0 also in a 24ft pontoon. You and others helped me sort the problems in that engine also. I got it dialed in perfect but in the end it just didn’t have what I was looking for. Thanks to you and everyone else for the help and advise.

    4.3l electric fuel pump conversion

    So the positive side of the pump should have two wires . One pur/yel from starter and one purple common hot. Is this correct? Also I keep hearing about a relay to take the strain off the oil switch but notice the schematic doesn’t have one, is this one of those lesson learned or is it just an...

    Ok I have read a lot about the 4.3 it’s pros cons and horse power but still have a few questions. 1. Can you put vortec heads on a pre vortec block and still achieve the same compression ratio?

    Small prop to avoid damage?

    I have a depth finder, but I also know I’m going into too shallow water , I usually cut the throttle going in, but sometimes when I push out it’s not far enough and I hit bottom a little bit even when trimmed up. Nature of the beast I guess, just wondered if a skeg guard would help making the...
