DF140 engine support

Lo all,

In advance of a long tow up to Easdale I'm looking for a specific recommendation for engine support.

I used to use a fantastic yolk fabricated by PD but it went missing. I have tried to make a replacement myself but out of wood, but it's not entirely convincing. It has a habit of slipping out downwards.

So I'm looking for recommendations , hopefully from Suzi DF140 owners, about what they use for support while towing. I've done a search and one of the answers i liked most was using a keel roller, but it doesn't look like there's enough clearance round the trim ram for that. I've also had a suggestion of having a 20 - 30mm polyprop (or similar soft but tough material) bar and jamming it in the yolk between the hinge and the tilt ram but it looks to me like that would keep the engine tilted too far up (I generally have the engine at about 45degrees when towing).

Any and all suggestions gratefully received.

I have a DF140 and this is my method:

Firstly tilt the engine to a position you are happy to tow with without risk to the skeg hitting the ground. Measure from the top of the two trim rams to the respective trim stops on the underside of the leg.

From a length of 32mm UPVC waste pipe cut two sections to this measurement.
Repeat the above from a length of 40mm UPVC waste pipe
Using a tube of Puraflex or Sikaflex smother the outside of the small tube with this and insert into the larger tube. Force as much sikaflex into the annulus between the two pipes as you can. Repeat this with the other two sections of pipe you have cut. Allow to set.

Tilt the engine up further and slide the pipes over each of the trim pistons. Tilt the engine back down until the leg weight is transferred 50/50 between the tilt ram and the two UPVC pipes.

Note I tried this with just single sections of 32mm UPVC but found they were too weak. Gluing the inner tube to the outer tube makes them a lot stronger. I can show you these tubes at Easdale if this doesn't make sense.

Can you post a photo of the rams... I have a couple of US My-Wedge supports from my old Opti that may fit. The Opti was a twin ram system

Hi guys.

Diver : that's a cracker. Might give that one a go.

Jeff: I don't have a clear photo of the rams unfortunately. And the boats down in Wales so won't be able to take a pic until the weekend.

Theres two rams, I think the diameter is about 16mm. The diameter of the cylinder (ie the base the support would need to sit on) is probably about 40mm.

If you reckon they'd fit you can PM me to 'talk turkey'

Hi Dan .... this is the item - but I suspect it is not suitable for yours . You use one and it slips over either of the two outer trim rams . My newer F150 has a single centre ram and I use a split type one.

EDIT :::::: Just read the blurb on the link I sent. Yes, it fits the DF 140 :-)

Likewise my boat is elsewhere but in the attached photo you cans see my 40mm UPVC pipe support and the lower ram body / ram cap is significantly larger - perhaps closer to 60mm diameter. My engine year is 2002 - not sure if they have changed the trim rams since, but doubt they would have changed much..?

I don't know the Suzi DF140 but wonder if this Yamaha engine support would work?

while looking for this link I came across this, I've not seen it before and have no idea if it works or is available:-

Prolly right: I'm kinda making it up by extrapolating from the 16mm diameter of the ram and even that's just from memory.

Haha awesome, that looks very similar to my UPVC pipe just with a Yam badge stuck on it!! Perhaps I should go into business!
