    Aq271c Engine wont rev past 2000rpm

    There is one other thing to check. With the #1 @ tdc make sure that the mark on the balancer lines up with the ”0” mark on the flag with the degree marks. It is pretty rare but the outer ring of the balancers have been known to slip.

    470 front pully removal

    If you can cut some of the deck out it would really help with what you have to do. You can always repair that. I have had to pull engines to do that in the past. It would help if you can run a 3/8“-16 tap through the 3 holes in the balancer to clear the threads. Depending on the thickness...

    Remove 190hp omc tilt motor

    Actually they are 3/8” hex. A short combination wrench either 6 or 12 point was my tool of choice. Sometimes a 3/8” universal socket 1/4” drive with a extension and driver handle after the bolts are loose. And of course, patience.

    How to replace a VP 250

    How to replace a VP 250

    I never tried it but if he swaps the suspension fork the entire 290 would bolt up. I would only stay with a single propeller model. The main thing is the gear ratio. It has to be a 1;6 to 1. Sierra # 18-3888 lower seal kit is all that is needed to mate any Volvo model lower to the mid...

    2001 VP 5.7 GSI PEFS no start

    I bet that the crankshaft is rotating at the required speed but the signal is coming from camshaft speed since the rpm readout is low. Are the signal pick ups in the same place as the original engine? Of course this is just a guess. Maybe someone can post a wiring diagram of your model.
