    5.7 Gxi-f outdrive issue

    Thank you dubs283, I have taken the lower unit loose from the upper. And the vertical shaft diid not turn when the prop shaft was turned. so I put all back together. Concern is that the problem started in the upper half. Repairing the lower might not be the only issue. thank You

    5.7 Gxi-f outdrive issue

    Hi Matt, Back at it again. In the lower unit, does the vertical shaft move up and down to engage and disengage the prop shaft? Would it be possible something let go in the shift linkage, therefore throwing it into neutra. Trying to understand how shifter works thank you for the help

    5.7 Gxi-f outdrive issue

    The coupler you speak about is good. The prop shows signs of hitting something in the past, thou very minor. Insurance says they may approve tear down to verify the problem. But if mechanical failure their out. Of course no one has time to even look at it. Exploring avenues to fix myself.

    5.7 Gxi-f outdrive issue

    Thank you, so if the vertical shaft turns and prop shaft doesn’t, I can assume it’s a gear problem in the lower unit. Is this something left for the experts or doable for a DIY? How can I tell if the problem originated in the upper unit?

    5.7 Gxi-f outdrive issue

Dropped lower unit, vertical shaft spins, prop shaft doesn’t. Makes me believe lower unit gears are...

    5.7 Gxi-f outdrive issue

    Thanks Matt my outdrive is an SX. The lower unit was pulled off And when you turn the vertical shaft the prop shaft doesn’t turn. This makes getting the ratio rough. Also no tags on the transom or engine give me a ratio.

    5.7 Gxi-f outdrive issue

    Thank you for all the input. It definitely is in the lower unit. Turn the prop shaft and the up shaft doesn’t move. The tag on the outdrive is SX-MBAC. But it doesn’t have the ratio listed. Also after looking at exploded views of the outdrive I could not find anything close to a clutch. Any...

    While out on river this last trip, running in about 50’ of water with the current. Running approx 28 mph and about 3000 rpm. Boat just suddenly felt like it went into neutral. Upon further investigation the prop wasn’t turning when put into gear. Of course being this time of year nobody can even...

    What prop should I use? What comes stock?

    I have 5.7GXI-F. It has a 14.25 x 17. It has a good hole shot and tops a approx 4000 rpm. I spun the hub and when asking around I was told I should be running from 4400 to 4900 rpm. Suggested going to 15 x 15. Does this sound right? Prop pushing a 26' tritoon. Dont know the gear ratio. Any...

    Trim tilt guage, temp guage

    These are on a 2005 tritoon (JC). Beede guages, the trim doesnt work at all and the temp jumps around. Not all the time but more than I would like. Are these related due to wiring? All other guages work just fine.

    2005 Volvo 5.7 GXI fuel issues?

    Ran great last fall when test driving. Over the winter we changed fuel filter, put stabilizer in fuel tank. Did a carpet change so everything including one tank had to come out. Put all back together, put in water and under load ran up to 3000rpm then sputtered, backfired. Like starving for...
