Stiff Throttle

[cashworth]

Hi, My son in law has a 2002 Crownline 215 with a Mercruiser 5.7 vortec engine and a bravo 1 outdrive .
He recently had a new shift cable installed along with some other engine work but now when he engages forward gear the throttle lever is very stiff to operate but is ok in throttle only mode.
I had a look a couple of days ago and found that by disconnecting the shift assist device on the bracket next to the carb, things became a lot easier (although not as smooth as my Volvo SX). The shift assist springs appear to be ok but are quite stiff to compress. Can he do without this device or has anyone any ideas?
We could of course take the boat back to the guy who did the work but he is on holiday and it is a 100 mile round trip and so it would be good if we could fix it ourselves.

Thanks in advance

Hi there, A few questions for you, Are you sure he has a Bravo 1 drive and not a Alpha one drive?

He recently had a new shift cable installed.

What shift cable did he have replaced? The cable between the shifter control handle to the engine? Or the cable between the engine and the drive?

the shift assist device on the bracket next to the carb,
Can he do without this device or has anyone any ideas?

The shift assist assembly is designed to be used only on the Alpha Gen 2 stern drive. Yes the shift assist assembly needs to be there for things to work correctly with the alpha drive system once everything is adjusted correctly.

Typically if there is extra tension on the shift handle, it's usually a misadjusted, kinked, restricted cable at one end or the other as long as all three cables involved are in good working condition.

The best you can do at this point is to patiently follow the service manual of adjusting the cables to see if it helps.

If you have an alpha, Start with page 2A-13 http://www.boatfix.com/merc/Servmanl/14/14a2.pdf

Also, the top cable in the photo, the black barrel nut needs to be turned 180, the cable needs to be laid flatter then how it is now, same with the shift assist assembly.

Good luck.

Hi Commander,
Thanks for that info, it is just what we need. Sorry for getting my Alpas and Bravos mixed up, I have only ever had Volvos and they never go wrong Will have a go this weekend.

p.s. I could not believe the news about Don S. I have not placed many posts over the six years I have been a member of this forum mainly due to the fact that I have been able to solve most problems by reading his information. He will be sorely missed.

Hi there Cashworth... Could you please provide serial numbers for the engine and drive. Using those we can identify exactly what you have (year of the boat is totally irrelevant to the year of the engine and drive, which can also be different years), making it easier for us to give you the right information straight up....

Thanks, yes Don will be missed day in day out here on iboats for sure.

Now if or when your Volvo ever gives up the ghost Just remember Don's advice will live on in the archives for you to reference back on if ever needed. And if you can't find it, we'll do our best.
