Transom

crusoe · 08 January 2014, 23:02

Any reason why I can't prime the transom then spray with polyurethane 2K useing rattle cans.

The Avon SR did they come with a marine ply piece screwed on the back of the transom to stop the engine marking the gelcoat.

I've removed the ply so that I can glass bolt holes from earlier engine fits just wonder if it needs refitting?

Thanks John.

Spraying no idea, the ply, yes it's original, check out the MacRib thread, a new one going back in there

If it helps, here's a pic of the new one I put on mine in the autumn. I applied seven coats of varnish to the marine ply, lightly rubbing down between each coat. Many people will say that's over the top but to an ex sticks and string man that's nothing!

One coat of epoxy would be a good alternative in order to protect it, particularly the edges and the bolt/screw holes.

No offence - and it could just be me - but couldn't that have done with shifting to the left an inch or so?

No, just an observation amd curiosity. There must be a reason for it. I've seen much worse - on my boat for a start!

Very amusing (v keen eye spotting it.) I would not let you in the house in case you noticed the paintings a mirrors I have hung!

Aha! So you'd like to start discussing engine offset to counteract prop torque (and 18 stones sitting on an offset console) would you?

Let me dig out the table of offsets.....

Actually, Mr Caton will likely be along in a minute. He's looking forward to drilling some holes in his shiny new SR4 transom and has been burning the midnight oil with his abacus and chalk over the past couple of weeks, doing some calculations before he reaches for his drill.

I'll let him take over on the subject of offsets!

Chris Caton · 09 January 2014, 08:16

its a mystery to me, but here's the chart, I'll have to make my mind up sooooooon though

You can probably tell exactly how many Guiness you'd consumed before you hung each item!

I know what you guys are on about with the offset, I've just made the new one for the MacRib, I had to look at it more than once and wondered why it was off centre, I've made it the same as original but the urge to centre it up was almost overwhelming, mind you I still haven't fitted it yet

Hang on!!- I thought I that was the reason the boat does not trim in a straight line!! What's all this nonsense about offset?

Nothing at all; complete nonsense.

That's what I think every time I'm blasting along perfectly trimmed in a straight line without a hint, nay even a smidgeon, of pressure applied through my little finger on the helm

Any advice on useing 2K polyurethane on the transom

As I want to fill the old bolt holes ect and its gonna look like a patch work quilt.

Has any one offset their engine so they could mount a small aux on the Seariders.

Thanks John.

This is probably a silly question, but why not centre the plywood plate and just offset the engine on the plate.

How boring would that be; perfect symmetry?

Far better to let everyone think you've made a cock-up and spark a bit of debate!

The truth is, I used the original one as a template and didn't even think about it....

Chris

that's what I've been wondering about, do I centre the ply and just offset the engine, or do I offset both by the same amount

my head hurts with all this thinking, it must be beer o'clock by now
