    Default swtd motor placement

    ok guys i am getting a jetaway soon so i was starting to wonder about motor placement so if i have to cut my driveshaft i only have to once. where is the best motor placement for my swtd? i have 800hp ford now but will be stepping up to 900hp with upto 500hp of spray within the next year. my motor is at 19" from the transom now.

    if you're considering the back of the boat, not the pod, the transom, mine is 19" from the back of the block to the transom. i wouldn't change engine placement. it "looks" like your intake is in the normal location for a sw, with the back of the intake about 1" forward from the end of the pod.

    just install the jetaway on the pump, put the pump back in to get the measurement you want.

    Dont move the engine, just cut the driveline to fit with the jet a way. wish i could get mine farther back. my intake is even with the pos but its only a 2" pod. I believe my engine is abot 22" from the transom. i will measure it to find out. it was a bitch to get the set up close with the engine forward. still more to do, but its cose.

    when i installed the jetaway and had the engine in it, i just took the drive shaft and boat to the driveshaft shop, showed 'em where i wanted it and let them measure so they knew exactly where it needed to be cut. got it back the next day.

    That's the best way to do it.

    mines at 20 inches transom to the rear plate, as far back as a top mount starter would allow. I have an extra 1310 driveline center piece, for a sw with jet-a-way. Measures 4 11/16 center to center.

    Why does everyone run the engine so far back in southwinds?

    Mine was further back than presently, by a good five inches. I feel the boat rides/responds better now than before, but other things have been done since. Only been off the trailer three times or so, ran out of summer

    ok sounds like the motor stays where it is. thanks everyone. i was going to cut the pod and set a lopro intake to get the hand hole out for a popoff but look like that wont be in the cards this year.

    How does your boat ride (just cruising) with the engine that far forward does it have and odd characteristics?
