Trailering Advice.

Hi,
i got fed up with inflating and deflating the SIB so got a trailer... my question is can i trailer a SIB with the engine attached? or would it rip the transom off?

thanks

Why not fabricate a bracket and rod to the trailer to support the outboard

Aerotec 380 - trail with a 15 Mariner on the back. Similar?

pierre · 27 May 2013, 19:42

very similar, mine is very high up on the trailer at the moment but i will drop it down more.
what support to do you have for your motor whilst you are in transit?

Used to trail a 25 on the back of my 3.8. Had a block to ensure the engine stayed up during transport. There is quite a long thread on here about engine up or down on sibs for transport.

I never had any issues.

should have added my engine is a 4 stroke 20Hp so not light one

hi i have 20hp 4s on honwave t40 and use home made transom saver and no problems ,very easy to make 2x exhaust u clamps welded between a length of round bar and cover engin end with pipe laging ,run with engine down and bungy strap between leg and trailor

If you could place at back trailer a wooden slat running tube to tube width for engine to rest there will be opt. Will need to trailer that combo with tubes well inflated though for transom/engine rigidity. Engine must be locked down with sufficient leg height with respect to floor when trailering.

Happy Boating

Think about it, what difference is an engine on a boat on a trailer, to a boat in the water? Engines do not float.

maxitope · 28 May 2013, 19:54

here is pics of home made transom saver padded end to leg other to trailer and held down by tight bungie works very well hope this helps.

wonder if i goto a local blacksmith they could knock something like this up for me..
maybe a slow walk round B&Q to see if i can get anything like...

maxitope · 28 May 2013, 22:30

made this one adjustable threads in and out to fit . if u could find somthing like and get 2xu clamps welded on each end then cover with pipe laging.

I often wonder about this. The manual for my boat says that you must not trailer the boat with the engine on though. The boat was sold to me from new and handed over to me with the boat on a trailer and with the engine on.

My trailer has a transom support and having seen the massive forces on the transom while under-way, I can't see any reason why it can't take the loads (like sudden jarring hitting a pot hole) while being trailered. I suspect the problem is that the boat gets most of its rigidity from being inflated. If the towing car threw up objects from the back wheels that punctured the tubes, there is a possibility that the engine would fall forwards (or backwards), then back out underneath the trailer. It wouldn't be a risk on a rib and less likely on a hard deck sib. But a possibility on any sib. If the manufactures feel the need to cover their arses then it makes sense to reduce the risk if/when we ignore the manual.

I might have missed it posted above, but you must support the transom of the boat with bunks. They can extend well beyond the back of the boat.

I used to tow mine with the motor mounted and no extra supports. Now I use a "Transom Saver", that I modified to fit.
