Steering system for twin engines

I am putting twin 150's on my rib. I have a single Seastar steering system at present. Should I just get a tie bar and go with that on to the second engine.

I do drive the boat in a lot of chop and the Seastar website seems to edge towards 2 rams linked if you drive aggressively!, obviously they cost more but I don't want a failure?

Quinquari fit twin rams as standard; we had a problem with one of them on a boat I was driving once so simply removed it and ran on the good one for a few weeks while it was sorted. Worked fine. However I guess this is a good example of why you should have two; in case one fails! (Wonder if having twin rams counts as having alternative steering in in the case of coded boats.)

Either way you'll want a tie bar connecting the two.

Mine is a single ram but only on twin 90 HP on a 6.5 m Redbay that will handle the rough stuff and no problems
My cylinder goes on the tilt tube

I have twin 150's and have the single ram with a tie bar with great results and no problems. Please note that you need the appropriate P/N's and tie bolt for that application but it is well below the 600HP limit.

Hope this helps

And me, but only got twin 135's, but it will get a lot of serious lumpy use, so hope the single ram holds out
Was hoping to launch before the new year but now looks unlikely

If you need a tie bar there's a guy on ebay selling new fully adjustable ones for next to nothing. I made an offer of 30 which he accepted. The quality is really good:

Yamaha Twinning Tie Bar for Outboard Motors (Not Inboard) | eBay

(Should fit other engine brands too)
