G2 200HP  M/N EC200FXAA S/N 5511604

Hello, this is my first post and I have questions if anyone has mounted a Permatrim onto a G2 motor.  My vessel is a 2120 Parker pilothouse which was formerly powered by a Yam 150 4S and now newly repowered with the G2 200.  This boat is stern heavy and I had a Permatrim mounted on the cav plate which helped a lot to get on plane.  

Can anyone comment if you've mounted the Permatrim on a G2?
I am concerned since the cav plate seems to be smaller on the G2 the Permatrim holds with the torque.

Any responses would be appreciated.

Vern, I am not a fan of installing any kind of winds on any ant- ventilation plate on any motor, since you don't know how that particular application is going to react in IMHO you will be better off by making the investment and real trim taps  to you boat,

Cheers

If your G2 is installed correctly, the anti-ventilation plate will likely be out of the water.

The motor was mounted correctly by my dealer and the cav plate does show correctly on plane plus I do have trim tabs.  But it still takes awhile to get on plane while adjusting the tabs.  Previously on the old Yam 150 with the permatrim, it would get on plane quicker and keep the bow down. 

When I discussed with my dealer, he suggested having one installed but thought I would see if anyone here has mounted one for performance results.  Once the holes are drilled and the plate installled, there is no turning back.  My understanding in checking with Permatrim, is that New Zealand boaters have experience with them....

What's the WOT rpms?
An overpropped motor will be slow to plane.  Want an absolute minimum of 5400 rpms, loaded heavy.

The 2120 Parker pilothouse is bow heavy, cabin helm forward.
Need a bow lifter prop such as a 4 blade RX4, but the lowest pitch they are avail. in is 16P.
Doubt your 2.7L G2 has the torque to spin one, try one with all the vent holes open.  Work from there.
Start takeoff from partially trimmed up, raises the bow, lowers the forward half water friction drag, increases speed gain.  Find the sweet spot for takeoff beginning trim, will take experimentation.

Stern lifting will only show the boat, both takeoff and WOT top speed.

The E-TEC G2 engine gear case already has a larger-than-normal anti-ventilation plate. The notion that adding an appendage to the already larger-than-normal anti-ventilation plate is going to produce a significant improvement in the planing characteristics of your boat seems quite speculative.

At WOT, 5800 RPM and 40 mph.  I am swinging a 4 blade 14.5x17 Turning Pt prop.  Dealer said he has had great success with them. Once on plane the boat moves great. The Parker 2120 is stearn heavy and the initial hole shot is slow getting to plane so I am in discussion with my dealer who has been around for over 30 years and very experienced.  He suggested trying some different props first then possibly try the whales tale or permatrim.  I have had good experience using the permatrim on three previous motors but wanted to reach out to any Etec users first who may have them installed.  Thank you for ALL comments, they are appreciated.

I highly recommend trying a Rebel.  In my experience with heavy boats, the Rebel has been a superior prop.  

As far as the Permatrim, I have one customer running them on G1's and really likes how they behave with a catamaran hull that was hard to plane.

Many, many, many have great success with hydrofoils. Permatrims and other brands. On all brands and models of motors.

Some folks hate them. Reminds me of the Chevy vs Ford motor brands wars.


Is there any way that the Permatrim can be clamped to the anti-ventilation plate of your motor for test purposes? If so, give it a go. If not, you might want to try a hydrofoil model that comes in a clamp on configuration. If it works for your application then that will give you even greater confidence that the Permatrim will perform similarly. Or stay with the clamp on model used for test purposes if it gives you the results that you are after.

Can't see why it wouldn't. It's "footprint" is going to be a lot larger than the G2's AV plate - thus at the right angle it will generate more upward thrust relative to boat speed. Certainly makes a huge difference on my G1.  Does the engine trim in "under" ie- negative trim, when fully trimmed down?
