Hi I have looked online for one of these, there not easy to find.
They don't even exist on the stainless marine website.
What do you think of the TH Marine Atlas lifters?
Thanks Dave

What are your thoughts? I'm guessing you and Geoff will be fitting.

Hi, yes I've looked at those as they have a built in pump. They seem to be the same as TH Marine's Atlas range.
What do you think of those as I have been offered a nice deal on one.
Thanks Dave

There are many jack plates and some of course better than others.
But - so important to be good on installation. Need a good true transom, not flexing or having any distortion. Then be prepared to loctite fittings/ fasteners on the actual unit - depending on make etc.
After that treat them well - maintain them! Drive well. Even be careful towing - i.e - don't expect to jack engine to highest setting and then drive hundreds of miles.
All logical - but often forgotten......

Thanks Gents, for the advice. Some good points there Adam, that make sense now that you have pointed them out.
Sadly Ross I am stuck with a 12" Atlas jack, nothing I can do now :/

In my experience the Atlas jacks have quite a bit of play, making the boat a little unstable, other than that im sure it'll be fine.
When the engines fitted, lift the jack to where you expect to be running and bounce the engine up and down from the back of the cav plate, you'll see what i mean

Hi Guys
Unfortunately I was a bit to hasty with my ordering, the joys of having the work of three men and the body of one :/
Anyway after a good bit of googling " atlas transom jack problems/ breaks/breakages/accidents" the only complaints I could find were regarding the pump leaking when people have driven some distance with the engine jacked up instead of lowered. Also weaker pumps in 2011/12 that have now been changed.
There seems to be a lot of praise for the self lubricating polymer rods over having to grease everything up.
Either way if I could wind back the clock I would have bought something else, but I can't. So I'm stuck with it.

Couple of options for your engine:
Stock 300XS flywheel : 19.76lbs, which Simon Motorsports can lighten by 3lbs
Stock 300X flywheel : 12.80lbs
DBR 300xs billet flywheel 11lbs
DBR 300x billet flywheel 6 or 8 lbs, depending who you speak to.

Hi, I have the 11lb billet coming as the engine ticks over ok with this one. I'll give you a shout when it arrives.
The exhaust tuner has just turned up, I'll buzz Geoff in a min.
