Author Topic:   Engine Tilt When Towing
wpr posted 06-10-2001 07:04 PM ET (US)   Profile for wpr  
I've just purchased a 1998 Montauk with 90 HP Yamaha w/ T&T. The package rest on a Magic Tilt aluminum (float on/drive on?)trailer. My concern is what is the best way to tilt the engine during trailering? Due to the trailer configuration a transom saver is not an option. The prior owner simply tilted the motor to the max tilt, dropped the engine locking latch down and lowered the motor down to rest the weight of the engine on the bracket and not the hydraulics. This is fine for the hydraulics but I am concerned about the transom. The engine when tilted up, seems like a pretty long lever. How does this affect the transon over the next 30 years? Is there a better solution or is everyone doing the same thing? Any ideas are greatly appreciated.
Thanks in advance, -Bill

wpr-I must have the exact same set up as you do. When trailering I do as you said, let the engine rest on the bracket. The dealer told me for storage to leave the engine in the down position. I noticed that if the oil resevoir is completely full and the engine tilted all the up, the oil will touch the fill cap.

I have a 99 Montauk and I trailer mine as both of you do. There are a lot of pros and cons concerning transom savers. In the 35+ years I have trailered boats I have never used one, but I have never kept a boat over 5 years so in the long term I am not an expert. In my years as a boat dealer I didn't even stock them nor reccomend them and have never seen a transom failure.

I have never used a transom saver; I tow with the engine tilted. My theory is that the moment arm for the motor relative to the transom is actually less when the powerhead is as close as possible to being directly over the transom --- therefore less stress on the transom . Works for me. Towed a Nauset with a 65 Merc for years and now an 84 18 Outrage with 150 Merc.

I used one on my last boat, a 15' hobie power skiff w/ 40 hp Mariner. The transom save deformed (read that as bent)the rear cross member of the trailer. That's what got me thinking about the forces that must develop as you travel down the road. These boats are tough and can probably take the pounding, but I didn't know if I was missing a trick everyone else knows about. -Bill

Bill-I am curious where your boat was originally sold(when it was new). My guess is Florida. I also have a Magic Tilt trailer. I purchased in Atlanta. My tongue weight was too heavy when I purhased the boat new. Have you had problems with that?
It is a nice looking tailer and the aluminum parts won't rust. I also like the white PVC guides for driving on the trailer.

My Mercury owners manual recommends the use of transom saver type devices and discourages the use of the locking latch when towing. Don

gawhaler - My boat was purchased from Crocker Marine in North Carolina. Tongue weight is not a problem. It is heavy but not excessive. You mentioned the aluminum Trailer will not rust - be careful, it will corrode. I noticed a problem area when replacing my side marker lights. They used the trailer as a ground. At the juncture of the light grounding tab to the frame the corrosion began. This trailer is two years old! The fix is to hardwire the lighting grounds back to the connector that attaches to the tow vehicle. Good luck.
