Re: Driving with trim in up postion

That is why I keep wondering if they have ever had it at at the full UP TILT Trailering Position.
It sounds like all heck, blows water everywhere and gets you nowhere fast.

He may be trailering in the Normal UP TRIM Position without knowing it would go even farther if they pushed the button harder.

lol yes when trailering the trim is all the way up, if it went any higher it would be touching the swim platform.

My Chaparral has a separate switch for the trailering position. The switches on the throttle will only raise and lower the outdrive to the limit switch. To trailer you have to use the trailering switch on the side of the throttle quadrant.

You can run your boat with the outdrive or motor trimmed up. If it's too high, you will hear the exhaust make an awe full noise and you won't get any bite out of your propeller. If it was low enough to move the boat then you are probably ok.

I should also mention that running with the drive too high up (trailer position) can result in the u-joints grinding on eachother because of their extreme angles.

Re: Driving with trim in up postion

If your drive is high enough to hurt the u-joints then your prop and exhaust are going to be right out of the water. You'll know it long before 30 seconds as stated in the original question and you won't go very far. I've done it. As soon as the engine starts you know it and shut it off or lower it right away before even getting into gear.

Not true on an I/O. I see people run with the drive in trailer all the time to get out of the shallow spots. On my boat I can't raise the drive to get even close to the water surface.

Almost hate to ask if the drive was turned very far while underway with full tilt up. RPM above idle and turning would be the most stress and most likely to cause problems.

And possibly rubbing against the bellows.

Hey guys... Little update here..

My throttle lever does in fact have 2 clicks when trimming up. But the 1st click doesn't do anything, I have to push it harder till it clicks again to start raising the trim. Why does it do that?

Re: Driving with trim in up postion

Sounds like it could be in the trim switch or limit sensor on the outdrive. It's on the port side of a alpha drive. You have to do diagnostic with a DVM to figure out which one is the problem.

The trim sensor wouldn't cause that problem but the limit switch sure would. Connect the wires that normally would go to the limit switch together and see if it works.

Re: Driving with trim in up postion

Thumpar, I think we're talking about the same thing.

Robert, The Alpha 1 gen 2 has 2 position sensors. The starboard side sender is for the gauge. The port side sensor is the trim limit sensor. This sensor controls where the drive stops when you're pressing the trim button to trim the drive up. When this sensor triggers the drive stops moving upwards and you must press the button harder for button position 2 to raise the drive to trailer mode.

Here's a few links that how useful info and may help you troubleshoot the issue.

Trim Sender switches. Replacing your trim limit and trim sender switches.

My trim button does not work. My trailer button works OK. It goes down but not up.

Or it could be a problem with the trim switch or a loose wire at the throttle.
Start with the obvious, easy stuff before you start disassembling the outdrive. :)

I agree on that. Bypassing the limit switch like thumpar said would be easy too.

Re: Driving with trim in up postion

Do you by pass it on the throttle lever or somewhere in the bilge?

You will need to check it at both ends of the PUR/WHT Wire.
The Limit switch connector will be close to the Drive behind the engine. PUR/WHT and BLU/WHT Wires.
This should get you started.

PUR/WHT = Running Trim Up (Half)
BLU/WHT = Trailer Trim/Tilt UP (Full)
GRN/WHT= Trim Down
RED/PUR = 12v Power

Re: Driving with trim in up postion

I know I will get beat up for this but, when I was a kid I would take my Dads boat out at night and with the lights on I would put the I/O up all the way, like it was on a trailer and give it gas and send water up maybe 20-30 feet in the air. Your right in the fact the boat does not move forward, it barley rocked the bow but blew the water up in a huge fan. That boat has never had a problem in 40 years and I did this like 20 years back.

We all have done it at least once, at least we claim it was unintentional.
Let's hope your Dad doesn't read this! :joyous:
But that is also why we were questioning earlier, if the OP actually had it FULLY UP!

...I was wakeboarding this weekend with a friend driving, he put the trim up for a moment in shallow water to pick me up. When he launched he left the trim up and didn't lower it for 20-30 seconds or so...

I can't understand how the Driver didn't immediately notice something was severely wrong or how the wake-boarder was ever pulled out of the water. Full Normal Trim UP, and a water ballasted boat might work,
but trimmed up to the Full Trailer position seems questionable. :confused:
