Hey guys. I want to install an outboard bracket on my 15' tri hull. I've got a 5hp 4 stroke I want to put on it,and I'm looking at the one they sell here on iboats made for freshwater and 4stroke motors up to 5hp. It's spring loaded to help with lifting the motor. web page My motor weighs 56lbs. Will this unit do okay?<br /><br />Some more questions? Does this come with hardware, does anyone know? Also do the bolts go all the way through the transom with nuts on the other side or not? If the bolts go all the way through, how do I waterproof the holes? 3M 5200 or something? Thanks for the help, I've never installed one of these before. :)

Re: Outboard bracket help

I have the same bracket.<br />Mounting bolts did NOT come with it when I bought mine a few years ago, but the descrition on the web link says they do now.<br /><br /> Yes they go all the way through the transom, sealed with 5300 or 5200 (easier to remove). <br /><br />Hardest part is locating the correct mounting location.<br />Set mine up to place prop below the hull when the bracket is lowered about half way. This keeps it high enough for easy operation.<br /><br />Mount the motor on the bracket and use a hoist or two friends to hold and locate the correct height for your boat. Then c-clamp the bracket in place and mark the exact hole location.<br /><br />PLease be aware that the instruction tell you to remove the motor from the bracket when you trailer the boat. It is not designed for use on the road, and I believe some members here have had trouble when doing so.

Thanks for the info roscoe. That's just what I was looking for and I'll follow your advise to mark the hole locations. Have a great new year! :)

Re: Outboard bracket help

Mine is also very simular but I have two 20 HP two stroke brackets hooked together. Even with this motor pretty hard to lift but my motor is a 15 HP long shaft. Also keep in mind some brakets have as much as 15 inches of vertical lift and some as little as 9 inches. If you need the long lift then get it but if not I think the shorter lift brackets the motor does not bounch around as much while on the road. <br /><br />Another thing to think about is if your transom is not vertical but at a angle like most they make models that allow the motor mounting board to be adjusted vertical. If the transom is at a slight angle like most then all the brackets will work but if it at a more severe angle then you may want to get the one you can adjust. I would not buy a bracket that is not rated for at least twice your motor weight. <br /><br />I trailer with my motor on the bracket all the time but do strap it down with a strap.

Re: Outboard bracket help

Thanks for the info Boatist. My 4 stroke motor weighs 56lbs. and the bracket is rated for 120lbs, but it also says to use no more than 5hp if the motor is a 4 stroke. What difference does it make? Why are 4 strokes harder on these brackets than 2 strokes? 4 stroke motors certainly don't create more torque than 2 strokes. I like the idea of doubling up on the weight rating. I would like to trailer the boat with the motor in place, but I don't want to break anything.

Re: Outboard bracket help

The only difference with the 4 stroke is they weigh more so someone just looking at the HP rating can exceed the weight rating. I used my bracket since 1981 but have had a few problems with it. Mine is made by Garelick. I replaced two springs and also several of the bushing the spring rides on as they had cracked. When they break then it can deform the springs.
