    Default Kodiak 460 questions

    I just purchased an early 90's Kodiak 460 with a closed cooling system. It was originally installed in a Design Concepts alum river boat. I was surprised to see what looks like a stocker type front sump oil pan. I will be using this engine coupled to a Berk jet in a 23' alum work skiff in Alaska. I envision slow speeds, no more than 25-30 mph due to the design/weight of the hull. Is this pan acceptable or do I need to get a larger capacity jet boat pan and different pick up assembly?

    It also has the original Kodiak mounts but is missing the actual "interface parts" between the rear mount itself and the stringers. The alum bell housing is there but not the mounts. Is there a source for these or anyone have a pic of what is needed to complete this install?

    I hear this engine is about 320 hp stock. If I'm looking for max low speed grunt (3500lb boat with full load of salmon which could be up to 5000 additional pounds, planning not necessary but bucking a 8 knot current is!) is updating the cam/intake or head mods going to help much or should I just leave well enough alone? Any other recommended mods for reliability such as ignition or carb (currently has a Holley).

    Thanks

    Lance, Any engine will certianlly benefit with a larger oil pan so a larger oil pan should be something you should consider. What kind of front mounting system do you have on the 460 Ford? This will help in selecting a rear mount set up. The 460 Ford came stock with a timing chain assembly that is 8 degree's retarded from the factory to meet exhaust emissions. A simple change is to install an early model timing chain that will allow you to install the cam straight up. This modification will give you approx. a 40 hp increase over what you have now. What size carb do you have on the engine now? Inginition and intake manifold is always a good up grade but given the rpm's the engine will running at manifold selection is going to be a little tricky. We want something that will make good bottom end torque because of the size of boat you are running and the rpm's you will be crusing at. MSD is always a good choice on inginition but there are other choice's that should be considered. Pertronics is a less expensive choice. Am I to assume that you are running a Kodiak pump. What size impeller are you running.

    Greg,
    The front mounts look very similiar to the adjustable mounts on my competition ski boat. Single separate mount on each side that has the ability to both adjust upward or to move the engine side to side. The rear is a bell housing that needs some type of feet to attach from it to the stringers.

    Unfortunently, the only jet I have available is a split bowl Berk that I plan to install in the set back position with a SDR reverse bucket. Any suggestions on what impeller to run and intake manifold with this engine/pump set up? Trash is not a consideration in the water I fish although we are fishing in very silty water.

    The timing chain is easy enough so I'll get that swapped out when I do the pan. Is there any pan that has any advantages over another? Miloden or Dooley for example. I'll also run the Holley carb number to see what cfm it is.

    thanks!
