View Full Version : Throttle/Shift
08-03-2004, 06:42 PM
I recently installed a new Morse shift/throttle I got from skiDIM, it's a MV-2 (the standard single lever with round ball) and yes, it's a vast improvement over the worn out "T" handle shift that came with the boat...it seems it's TOO easy to accelerate/decelerate as it wants to decelerate by itself....I've read and re-read the install instructions looking for some sort of "drag" control that would make it a bit stiffer but with no luck...anyone have any ideas...I've already removed the sring return on my carb and that seems to help but it still wants to slow down when going 1500 rpm or slower (at 3000-4000 it stays put pretty much)

I'm sorry that I don't have a solution, but you might want to consider putting some sort of return spring on there. I got sick of the throttle return on my boat, too, but didn't remove it altogether. Instead, I got a less tense spring of the same lenth from Pep Boys. I seem to remember someone saying that if your throttle cable breaks, you'd want some sort of spring on there. BICBW.

Maybe if I take the throttle cable and kink it a few times and then pour salt water down it that will provide just the right amount of drag I'm lookin for....just kidding :eek:
I agree with re-installing the spring on the carb...I just had to see if this would help...
There is a spring return thing in the actual control but I'm not quite ready to start monkeying with it yet...it's just such a vast improvement over the old one that I'm just thrilled to have reverse! as well as full throttle in forward...

Wes, sorry, I was talking about the one about midway down and back on the port side of the engine (below the carb). At least that's where it is on the 351.

Quite allright, quite allright...my idle return spring is up where you'd expect it to be on the side of the carb (holley dual pumper) but someone's been stretching it so I'm not sure what the original tension is supposed to be...the shifter has something refered to in the install manual as a "dwell block" that apparently assures the engine is at idle while the shifter does the shifting - this dwell block is just a nylon sliding thing backed up by a spring that absolutely places the throttle at idle...perhaps this can be "loosened up" with some judicious jiggering....like I said, I'm not quite ready to garf up my new shifter just yet....Wes

A lot of people will stretch the return spring to get the desired result. Mine was so stiff that I couldn't stretch it. Not sure about the other part you mentioned.
I had the same problem on my 98 Maristar direct from the factory. Dealer said it was for safety so that I had to keep my hand on the throtle all the time. I found it funny because none of the other boats that I have owned or driven had this great feature. I found that there is a clamp that is made to put tension on the cable. It costs about $10.00 and is worth every penny. Really simple clamp. I found it after talking to a tech at morse, who is now someone else. Check with Morse

Weird, Bob. My Father in Law's 98 Prostar doesn't have any return on the throttle. But maybe the previous owner took care of it. Sounds like you found a good solution though. The return feature is a little different on the GM boats if I remember correctly.
I thought about messing with the return spring but someone told me about the friction on the cable is the best way, you don't want to mess with the throtle return spring. If the cable falls off or breaks you want the throttle to come back. Normal operation the vacuum will pull the carbs open without a return spring assist. If my childhood memory is correct......I learned this the hard way.

Can/will you elaborate on this clamp? Can/will you offer a snapshot of the clamp? I think I would like to at least partially disable that wonderful safety feature.
It is a very inexpensive solution that is great. Here is a picture of it. It can be found at www.shipstore.com/ss/html/MOR/MOR44386.html or you can search for a Morse Cable Brake #MOR 44386. :steering:

Thank you BobL
That will help me a lot. Iím on it..:dance: !!

I purchased said clamp, works like a shot!

I forgot to tell you where to get one....duh
Go to skiDIM and search "cable brake" or by part #2432.
These folks are first rate!

I didnít even think of them. I like DIM a lot. That link above has them as well

Mark, since you and I have the same boat/engine, $.50 and a trip to pep boys will fix the problem. Just my $.52. :)

I just got off of the phone with DIM. He told me, (I didnít pay attention to his name), (character flaw)
I could use the clampÖor stretch the springÖ or replace the springÖ or I could do what he did. He just took it off.

I've got a 92 190 with the same throttle return setup. A couple years ago I read on this site that a cable clamp (with nylon lock nuts - "Nylocks") could be placed on the throttle cable to provide friction. Some put it up by the throttle control, some in the engine compartment. I put mine in the engine compartment (easy access) but even lightly clamped it seemed to make the trottle too stiff. Part of the decision to take it off was that I figured if the cable breaks between the control and the clamp, the throttle won't return even with a carb spring on it, so it's probably best to install the clamp as close to the throttle control as possible. I could be wrong but that was my observation at the time. If anyone knows how to remove the spring inside the control I'll give that a try rather than reinstalling the clamp.

What year is your boat? is it an EFI??
08-27-2004, 05:21 PM
the reason that I ask is the guy at DIM told me the spring is hard to get to with injected motors. Thatís Y the clamp is an attractive alternative. My last boat had no spring. The other boat I ski on has no spring. My boat has a spring, but itís now in the glove box. Iím giving it a try like that and may install a weak spring.

OOPS just saw you have a 92. Port side of your motor in front of your throttle cable is a 3-4Ē spring that returns the throttle to idle automatically if you let go of the throttle control. So if that spring was removed Ö :wavey: By By issue.
But if you remove the spring you are in the same boat in the event of a throttle cable failure. But like I was saying , my last boat had no spring..

Couldn't stand it and re-visited the issue last night. With the cable and spring disconnected I could still feel spring tension at the throttle control. After closer inspection of the carburator I noticed a torsion spring wrapped around the throttle shaft itself. It felt like it had plenty of tension to close the throttle in the event of cable failure so maybe there are no worries taking the return spring off after all.

My spring is now in my tool box
