Does anyone have an opinion about Globe Drivesavers? Will they actually "reduce noise and provide a smooth, quiet ride?" They are not cheap, I'm just trying to find out if they are worth the money. |

I have not had success with them. It sounds like a great system, but every time I installed them it created a vibration in the driveline and I had to remove them.
A properly aligned motor does not have any shaft or coupler noise so I don't know how much quieter it can be.
If you ask enough people I'm sure you will find someone who disagrees with me, but I see no advantage to them and no reason to spend the money.

Thanks for the heads up Rick. My engines seem to be properly aligned and fairly quiet in forward. In reverse there is a whining sound that seems to be coming from both (recently rebuilt) transmissions, but I think that may be normal for 1986 72C velvet drives. |

Noises in reverse are normal, and they aren't consistent either; my port tranny is much louder than the other one.
Agreed with Rick on these things; they tend to wear out the stuffing box instead. Prop shafts MUST be properly aligned! There's no excuse--or Band Aid--to compensate for mis-alignment.

OK... I am at that point in my final stages. As it turns out the shaft was rubbing the stuffing box shaft tube where it bolts to the fiberglass hull and before it passes thru the hose to the packing gland. With V-Drives, can I adjust the rear motor mounts to angle the shaft so that it centers the shaft in the hole of the new tube, OR is it more involved than that?
BTW: The old stainless piece was so worn, I am surprised it did not allow volumes of water to enter the hull. Apparantly the hose was on enough to prevent that. |

Yes Al. The alignment starts at the shaft. Since that is not adjustable you must center the shaft then everything else must align to it. These adjustments are possible although a little more complex if your v-drive is remote.

This should help.

Rick....You should know that you have pulled my butt out of the fire 5 or 6 times already in a big way...I really, really thank you...
I love the boat, I love going out and I love working on it...If I wasn't so old already and could support myself in doing so, I would work in boating...
When I restored motorcycles, I loved it but my wife probably had a different view 
Really..Thanks to you, the website, and all who have given me the insight necessary to get these jobs done |

Hi Rick,
Downloaded, bound and digested the entire manual. I would think that my V-drives are mounted directly to the block as I do not recall any mounting tabs ( I could be mistaken ). To that note, I would think that I am trying to align the shaft and coupler of the v-drive to the cutless bearing since those are the only two contact points inthe system.
IF they are mounted to the housing, then I would think it should be just a matter of adjusting the motor mounts to set the alignment...Is that true? Am I over-simplyfing something that requires a bit more focus? The setting I had inherited was so close to the shaft tube( like taking a 50 cent piece and a quarter totally connected at the bottom) it literally wore a hole thru the already thin stainless steel tubing wall |

Al, you are correct. If your V-drive is remote you will have two shafts. One from the transmission to the V-drive, then the propshaft which mounts to the V-drive.
If your transmission and V-drive are one, you simply adjust the motor to get the proper alignment. Just make sure you start with the shaft properly aligned in the shaft log. You may want to make a temporary fixture to hold it in place in the shaft log while you set the motor mounts. |

A Vee drive? I feel your pain (as in "pain in the *ss to adjust"!)
Good luck,

You know they say " slow and steady wins the race" IF IT WAS ANY SLOWER I'D BE GOING BACKWARDS...
It really IS a pain.. However, we took a lounge cushion and laid it across the batteries and stringers...you could ALMOST take a nap ;) |

Wake up! It's almost boating time.
