I am wondering if it is safe to trailer with the outboard hanging off the back. Is about 150 lb, a Suzuki 9.9 with electric start. Looks like it could be a real hazard going over bumps but it is pretty heavy for putting on and off the boat during trailering. Any ideas?

I'd have some concerns also but I don't trailer my boat. It is a lot of weight. Possibly you could put a ratchet strap around the mount and around the base of the stern rail to take some of the strain off.

I don't think you have much choice. I had a 79 lb motor and needed help to mount it or remove it from my fin keel boat. Maybe 2 really strong men could hoist yours onto the motor mount on a swing keel boat, but it would be difficult at best.

I'd suggest you leave it on the mount, with the motor tilted up as much as possible. When it's tilted, the power head, which is the heaviest part of the motor, moves inboard, towards the transom and directly above the motor mount. That moves the lever arm forward and off the mount. Then I'd use a strap to take some of the load off the mount, as Scott suggested, and attach a line to the end of the prop shaft to support it a little. Finally, I'd make sure the mounting screws are tight to the mount, and attach a safety line to catch the motor in case it jumps off the mount. Then just avoid hard bumps.

Alex, this has been discussed here in the past. Here are links to several threads. A lot of ideas have been advanced, but the general consensus seems to be that it can be done safely if the motor is well-secured. Adding backing plates, particularly on the inside of the transom to spread the outward load from the upper bolts, would be advisable for extended trailering.

Hope this helps address your concerns.

The trouble with a destination - any destination, really - is that it interrupts The Journey.

I trailered 2000 mi/year in 2 round trips with the motor on the transom, up, and motor and mount secured to the stern rail. Since it takes very little effort to tilt the motor, I suspect the long lever arm to the lower unit probably offsets the mass of the powerhead and very little benefit comes from tilting and not changing the center of mass. The only downside to tilting is putting the lower unit a little farther out towards following traffic. Do what makes you most comfortable, but definitely shift some load to the stern rail. I take it off now because my silly, 4X4 truck sits so high that the XLS motor stands so high in the bed that it practically falls onto the mount.

I also trailer with my Nissan 9.8 left on the motor mount. However, I use a couple ratchet straps to help secure it so that the bouncing is not an issue. Also the mount is secured to the transom with large backing plates to help spread the load.

I did not have any issues trailering from Washington NC to Charleston SC, nor from Charleston to Lake Murray SC. 9.9 2-stroke. I inspected but did not do anything "special."
