How high to tilt
I have a 2001 diablo 180 with a 4.3 volvo sx. I have faria gauges and the trim gauge changes color halfway up, is that a good spot (halfway mark) to stop lifting the outdrive when in shallow water. I know the mercruisers stop and then have a trailer button to lift all the way up. Just trying to figure out how high I can lift it while running.

Re: How high to tilt
Well dang... there's something else i dont know the answer to. Hopefully someone here with the Volvo outdrive can speak up. I would have assumed (okay, 'guessed') that the change in colour point was the sweet spot for level running but i really dont know. :(
I know with mine in really shallow water i lift the outdrive until i hear it burbling on the surface & stop there. |

the water pick-ups never come out of the water so it'll still be cooling the motor. At full up trim the end of the prop shaft is at water level and it is just about doable to change the prop while laying flat on your belly on the sun deck. I know because I've tried it. :yes_grin: I will add that you can run with the leg almost right up, But you loose all steerage at high levels of trim and the slightest stab on the throttle will send the bow to the sky (Tabs or no tabs) and your stren to the bottom! The best answer to running in shallow water I've found is to keep just above neutral trim (just above the half way mark) and run slow. You need at least 0.6m/2ft of water for your/our boat. Any less and you'll be stirring the bottom. if you have a transom mounted depth transducer you should take the reading very serious because you reading the depth right at the point of contact! at least my through hull transducer is 3ft in front of the leg. hence the "run slow" comment |

Re: How high to tilt
In my opinion, I always keep the drive all the way down when idling or driving slow off plane. For fast hole shots I always keep the outdrive all the way down. The only time I raise (trim it) is when I am coming up on plane and then cruising on plane. How far I raise it is a feeling. Get your boat up on plane and drop the outdrive all the way down. You will feel the boat dig in. Then raise it till you feel it get really smooth and just glide on the water. You will see the bow of the boat raise up slightly and your wake will decrease. For me, this is the sweet spot. If you go too high, you will feel it get rough again. Don't go too high or you will start to tear up your drive. There are lots of variables like how rough is the water, how many people onboard, weight load distribution, etc. so I don't think there is ever 1 exact setting to raise the outdrive every time. That is why I go by the "feel" of the boat in the water. Just my 1.5 cents!

Re: How high to tilt
I was just used to the mercruiser like I said would stop at a certain point that is where I would put it when driving it on the trailer. I just wasnt sure how high up the volvo could safely go while idling in no wake

Fully trimmed up the bullet is just above the keel line of the hull. The water pickups are still below the water but at this state of trim the boat is almost uncontrollable! If you’re that concerned about shallow water then my advice would be walk it in. Plus you look like a bit of a wally when your trying to load the boat with no steerage and the boats bucking like a bronco every time you touch the throttle if you're concerns are about striking the ramp then you need to trim your leg down when the boats on the trailer until you happy with the ground clearance on your skeg, then put a pen mark on the dial First shot is water level at full up Second shot is keel line at full up Hope this helps |
