current broadsiding

I come upstream through a draw-bridge and after a 100 yards my slip (floating steel dock) is directly perpendicular into the river on port. The river (opening) is probably 70ft wide with 30' slips on each bank and about 10' deep in the center.

I'm in the 2nd longer finger slip in front of the big building N of the bridge on the left. River flows N to S at that point.
Tricky landing with a sailboat.

jaschrumpf AFAIK, there is no single-lever "modern" shifter for the A4 and tranny. The question was raised a while back on the Moyer Marine A4 forums, and no one had heard of one.

When is the current broadsiding you in your approach?

single handle control

Is there a Single Handle (side mount) Control available for these A4's. Similar to the "modern" outboard speed boat controls that engage the tranny in forward and control the throttle when pushing forward and engage in reverse and speed up throttle when pushed aft.
I have to do this going forward and reverse quick while trying to land a 32' 12,000 lbs vessel with a 6 to 7 knt, running river broadside. My little two bladed prop on my 30 hp Universal doesn't stop the boat and the two handle/lever takes a lot of time moving back and forth if you only have seconds to get it right.
Never had that problem with the twin screw old Chris-Craft as I could run her in fast and gave full throttle reverse to brake her for a soft landing, but he sail boat is different.
Where to get a single control and can it work?

jaschrumpf Yep, the Paragon direct drive transmission. That's the one.

EJO I know this is an old thread, but as I have the same problem and need a clarification. I just want to know if everybody here is talking about the Paragon transmission when talking about the A4 tranny in the previous posts.

jaschrumpf It should be pointed out that on the A4 there is a definite detent going into forward -- you should feel a "click" or "thunk" going into gear. It should take a bit of effort.

Going into reverse, there is no similar detent (you will feel it coming back out of forward, though). Reverse is a different animal altogether, and the shifter essentially acts as a brake lever of sorts, though you shouldn't have to hold it in place.

This is the basic setup: forward has a three-fingered "claw" that has to slide over the detent to grab. To illustrate, make a circle with the thumb and index finger of your left hand and make the "claw" from the thumb, index and middle fingers of your right. Place the "claw" on the outside of the "O" and push the "claw" over it so that they grab on the other side. That's the "detent" you feel going into and out of forward.

Reverse is essentially a brake band that grabs a rotating cylinder to give you reverse (a 2:1 reduction, usually). When you pull the shifter back the claw pops back over the detent, then the brake band tightens to give you reverse.

There are two separate adjustments on the A4 tranny for forward and reverse, but they are both very simple and easy to make (depending on access). By all means, head over to the Moyer Marine site, and get Don's A4 manual while you're there. It's well worth the $40 or so.

Good luck!

msmith10 A4's are inherently harder to shift than most transmissions. However, they're not that hard. As previously mentioned, you should disconnect the shifter cable from the shift lever on the side of the transmission and see what it feels like. Is the cable still hard to move? Is the transmission lever hard to move? If it's fairly easy to shift using the lever, the problem is in the cable. If it's still difficult and the cable moves freely, it's in the transmission (more accurately, reversing gear). I suspect your problem is in the cable. It would only be hard to shift both ways if the unit is "overadjusted" both ways. In other words, if both the forward adjustment and reverse adjustment are too tight. If it's in the transmission, it's reasonably easy to adjust. This is really a very simple unit to work on. I'd recommend you go to the Moyer Marine site which is dedicated to the A4 (google Moyer Marine). The forum there is a wealth of info just on the A4.

sailingdog It depends... in many cases a dry lubricant is a better choice for cables, since they're less likely to gum up the cables. Some of the better cables come with a teflon insert to reduce the need for lubrication.

theredboat Thanks everyone for the advice. I'm pretty new to this, so I really appreciate the help.

I didn't use PB Blaster to lubricate, thankfully. I only used it because I had a hunch that some of the rust build up on the A4's shifter was causing the sluggishness. I blasted it, then used a wirebrush to remove some of the rust, but it didnt seem to help much.

What's a good lubricant to use on cables and the A4 shifter?

I will report back tomorrow when I have a chance to try and move the shifter without the cables attached. Thanks!

sailingdog I'd also point out that PB Blaster is not a lubricant. It really shouldn't be used to lubricate control cables.
