Upside down engine

[San Antonio Cop]

My friend is planning on getting the bottom of his aluminum duck hunting boat coated with spray-on bedliner. He wants to know if it would be ok to turn the boat over with the motor still attached. He is a newcomer to the boating world and really doesn't want to take a chance messing anything up if he has to remove all the control cables that would have to be removed. Thanks in advance for any info you guys can give him.

It shouldn't hurt anything IF, and ONLY IF, there is absolutely no water left in the casting cavities of the lower unit. Water in the mid-section or lower unit can dribble up into the powerhead, causing all sorts of issues...<br /><br />- Scott

What if it slips off? Also it may place undue strain on the mounting bracket from the leverage weight of the motor. Personally, I would remove it.

What's involved in removing a remote outboard with tilt from a boat?

Not too complicated. Remove fuel line, disconect the harness (red connector on port side of the motor), and take off throttle and shift cables, and pull the steering cable off. After that it's just the 4 bolts holding it to the transom, you may have to take these off before you can get the steering off.

Not to bust a bubble here, but tell your buddy that putting a spray on bed liner on the bottom of his boat is like applying power disc brakes. I know, we did it to a friends boat, and when you throttle down, the boat comes to a very sudden stop, he also lost top end speed. Just the voice of experience hoping to help a fellow boater

That might be a good topic to post in Boat Topics forum Jim. My fishing Bud was thinking about doing the same thing and his 18' Sea Nymph. Think I'll tell him not to.....

Re: Upside down engine

Just out of curiousity, why would he be wanting to coat the bottom of the boat with spray-in bedliner? If the goal is to quiet it down, why not do the inside floor of the boat (or maybe much of this aluminum isn't accessible?)?

Re: Upside down engine

The object is to stop the boat from leaking. Also the boat has an inner hull that would have to be removed to get to the inside floor.

Re: Upside down engine

The bedliner on the bottom is a good idea, but I just used some really good quality oil based paint. Power washed the hull and brushed it on with 3 coats (you could use a roller or paint pad). Did a little extra on rivets. It sealed those pesky leaks right up and has been working for 3 yrs. Cheaper than bedliner I would say.

Re: Upside down engine

Cloverdale paints had or has a product called iron oil, a clear varnish that I understand was used industrially on aluminum aircraft wings to prevent corrosion. Might be worth looking into for aluminum boat applications.

Re: Upside down engine

docdoc - what was the product that you used called?

Re: Upside down engine

Seal the bottom of the boat with "Gluv It". It is available at: <br /><br />www.westmarine.com<br /><br />It works great, I've used it many times.<br /><br />Bedliner material is a BAD idea. You will lose a consierable amount of performance.
