Yes, thank you for the advice, I will keep this in mind ;-)

Probably will build a rail box out of carbon...

Cheers Mate,
I saw the mounts, very nice, but not what I need for this application. I will have to build them from scratchfrom carbon plates, as I also need to keep the engine as low as possible for both CG and hatch clearance...

I have a brand new pair of z dives installed in a 70 inch phantom with gearbox and inline whh zenoah.I am having a problem filling the drives from the bottom with the adapter kit supplied by mhz.I screwed on the fitting but when i inject the oil it only comes out of the propshaft and no oil exits the breather at the top of the drive.I see that the instructions say that the oil must exit the propshaft and then you continue filling until it exits the top of the drive.Did anyone have a similar experience i tried to keep injecting it but the force required only makes the hose slip off.I tried emailing mhz germany but i have gotten no response as yet as shirley is not well.

I hve a pair of z drives installed in a 70in phantom hull with an inline whh zenoah.I am having a problem filling the z rives version 111 with the oil.I have the adapter kit that I got from mhz germany but when i fill the drives with the moly lube oil the oil comes out of the propshaft as per the instructions but the problem is that i cannot get any oil to come out of the the top of the drive through the breather hole as per the instructions.Everytime i attempt to continue filling the drive with oil the hose keeps slipping off as the force required is very great.I cannot see this as normal.Did anyone have a similar experience with this .I have tried calling and emailing mhz germany to get advise on this but I have had no success as Shirley is not well.Can anyone shed some light on this problem that I seem to be having.jason

I had an issue with that on my S6's (same setup basically) and I completely removed the top, breather screw from the unit and went REALLY slow when filling the drive. Too much pressure too quick and POOF...oil EVERYWHERE! LOL

If you want you can also put a small zip-tie on the nipple fitting barb over the fill-hose from the siringe. That should help...but most important...take your time when filling. Going too fast makes too much pressure.

sorry to ehar about Shirley! I hope she gets better in a hurry!!!

Take a look at the NXT Drive - https://www.mhz-powerboats.com/shop/...t-z-drive?c=70 I have yet to run one though MHZ have it rated at 6hp. MHZ have long exagerated the power capabilities of the older drives (they once did a build with a pair of stern drives behind a 24hp 125cc Rotax cart motor). Though these days I think they have a better handle on what their drives are capable of. All the stern drives could handle a stock Zen and the bigger drives should all be fine with a Mod Zen. I dare say the NXT will be the ticket for you!!

Mart - have also ordered the exhausts and some other parts from Frank. He treated me good, thank you ;-)

Where did you order this drive from? Can you link the website? Thanks.

These are an expensive, but great option for scale and performance for our model gas boats.

This month I purchased two new Z-drives from MHZ Germany: will be using these parts for building my new Apache (Cigarette Racing 46' AMG replica), on the basis of the 58' hull from Mart in UK.

My objective with this thread is to collect your own experience with these drives, in order to give answers and pictures for many questions I frequently read in threads.
Also, your precious experiences could really help me do the best possible job in this build, I will not deny it!

The main questions floating around on these Z-drives are:
- what is the maximum power they can handle? Most say 1 modified Zen260 or RCMK Evo
- using these parts as surface drives: experiences on placing these drives higher or lower on the transom, in respect to the hull. (and how this influences handling)
- experiences (pictures and video PLEASE) using the Quicktrim option (servo actuated drive trim)
- possible modifications (reduction) to the upper flat surface on top of the propeller area.

Thank you if you will want to share your experiences on these parts- Cheers!






Hi!
I used the stern drive of the mhz with a 35cc MATHE. They hold the effort until they unravel, the second exit to the lake after the beginning of a strong accelerated gear exploded inside the stwrn drive. They are very well made but not for a power greater than 26cc.

I imported a few dozen years back. RCM Stern drives have been out of production for over a decade. MHZ Z drive is the only option and virtually an identical drive.
