Well after inspection I see iv got 1 busted mount

Iv ordered a roll of nolothane and am going to machine up replacement ones and get rid of the saggy rubber ones.

Also iv ordered a new centre console to replace my cracked one. Really cheap too surprisingly.

Wow that's horrible, wouldn't have expected an engine mount go as soon as this one did.

Wow! you better take a good look at your driveshaft splines and the engine coupler!

Yea spline looks ok luckily. Iv ordered a roll of Nolothane bar and will machine up some new ones. I'm going to round the ally hex head and sleeve the new mounts with a Teflon sleeve.
Failing the Nolothane what do you guys think of a Teflon mount..

Good point on mentioning to look at the driveshaft splines and the engine coupler, definitely have to make sure everything else is in check before going back out on the water.

Even better question, i fear it being a wide-spread problem, it's things like this that always has me observing and not taking action on buying something right away, rather waiting to see how things turn out.

I reckon the spark engine mounts look a really good design. They are at least captive. Most other mounts just rely on the glue between the rubber and steel. Playing hard in the surf make engine mounts a consumable item. I broken heaps on other skis. Check them everytime.With this and another post it looks like Qcustoms plays hard. You play hard you break stuff and maybe make it stronger, that's part of it. Sounds like Qcustoms is happy with that. Looks like you might have planted the nose in the sand. That happens. I've seen much worse from that.

Is there some different material you guys would prefer that they use in effort for a stronger mount?

Well I replaced all four mounts with brand new nolothane rubber machined ones. Snug and good feel. Defiantly won't break in a hurry.

Tbh guys I wouldn't stress too much re your mounts. Remember I ride VERY rough in the surf. I'm airborne more than in the water.

Glad to see the new mounts and best of all an owner that can take the blame for the damage due to treatment of the unit.

On the subject of engine mounts....

Just replaced my hull after a massive hit, and I'm in the process of finalising the job - however, an inspection of the routing of steering and reverse cables showed me that I have reversed my engine mount trunnions or mount blocks and caps.. Not sure if it will have any impact, but now scared to go any further.

By reversed mounts I mean the outside face is now on the inside. The mounts appear symmetrical, and I cannot for the life of me see what difference it will make. Since I have everything mounted and torqued down to spec and the engine alignment done, I'm not wanting to disturb things. Must have been having a 'seniors moment' when I reinstalled, even marked mounts and positions as well as took pics before I ripped it down.

Anyone seen/done this before?

If you mean the top clamps that sit on the rubber engine mounts no difference
The rubber mounts are offset and flat side goes down
