What damage if any am I doing to my Merc. Alpha One I/O starting the boat on the ramp just out of the water? Typically I run the blower while we uncover the boat, take tie downs off and load the coolers and kids in the boat. I drive the trailer and back it down to the water's edge and then unhook the bow strap, hop in the back of the boat. Then I yell to my wife backing the trailer the rest of the way in to wait until I make sure the boat starts....nothing like floating off the trailer and then jacking around with getting the boat started and drifting into others. Anyway, I get the boat started and then I just yell, back her in and within 20-30 seconds the lower drive unit is in the water. Am I damaging my impeller or anything by doing this....running the enginer out of the water for those 30 seconds? Thanks.

Yes, running the impeller dry will quickly ruin it, even only a couple seconds. Wait until you are in the water to start the engine. I'd also change out the impeller now that you've run it dry a few times, or at least change it out this winter.

I agree TOTALLY with Aaron. How old is the impeller? It may be due to be changed anyway . . .<br /><br />You can still run it before she floats off. Just have your wife back it down until the ventilation plate is covered and then start it. The boat should not go anywhere at the point that the water intakes are first completely submerged.

BTW, just a tip . . . You'll get some people a little cranked up if you post the same question in multiple sections. The proper place is probably the Merc/Volvo section, but this one is a very close second if not a tie for first. Oh whatever, but you get the picture. ;)

Rinker,<br /><br />One thing I don't understand.<br />Why don't you have a line from your boat to the trailer, or throw a line to the dock?<br /><br />That'll keep your boat from floating away, and you can take your time starting the motor in the water.

How about the engine water pump? I think what you need to address is why you don't have the confidence that your engine will start.

I wouldn't do that. You need that water to keep everything cool and to keep the impeller from spinning without the water. You're going to wear your impeller out faster without the water.<br /><br />I'd recommend doing it like everyone else...back it in, submerge your lower unit, then start it up. If you're having problems drifting into others, have the wife and kids hold the mooring lines while maneuvering the boat into the water.<br /><br />Everything I've ever read has said... don't run your motor unless in a body of water, tub, or muffs... <br />--------------------------------------------------------------------------------<br />Posts: 80 | From: midwest | Registered: Jul 2005 | IP: Logged | <br /> <br />DJ <br />Supreme Mariner <br />Member # 5471 <br /><br /> posted July 29, 2005 01:06 PM <br />--------------------------------------------------------------------------------<br />It will ruin your impeller, if it already hasn't. You are setting yourself up for a very bad day.<br /><br />--------------------<br />We're all here, because we're not all there!
