Re: hull extension in progress with picks
hi guys.......sorry i was away.....
as noklu said it was mrs oops bday....so i was spending some time over there, and she wont let me post on her computer any more, as i kinda get caught up on the action here. !
ok....more updates.....just quickies. i just came home to get the bravo 3 drive cause i might have sold it.....then its back to the shop.
as noklu said....we may, or may not have found the cause of the vibration. i have found nothing i can point to and say......eureeka....thats it. in stead....just a lot of discrepancies that may or may not have addded to the problem...
1. wrong coupler....
this can be a cause of vibration because of the shaft not fitting into the coupler far enough....however....it went in plenty far and the alignment was great....so i cant see it being a major factor.
2. coupler slop...
there was sme play between the coupler and the drive shaft....not much...but some...
there is less with the new coupler supplied by i boater robj....(way to go rob)
the new coupler is the mercrusier suggested for the application, and the shaft goes in an extra 3/4 of an inch.
3. spring washer....
i had a half cracked spring washer......this is the washer between the flywheel cover mounting surface and the transom plate mount.
it is inserted inside the phenolic washer....the old one was broken slightly so a small part of the spring was missing......these were replaced.
4. motor mount isolators....
new ones were installed as the old ones were just loaners....the old set were worn out, but still did the job.
on monday...we spent the whole day searching for some studs to attach the flywheel and the coupler. the new system wouldnt take the standard grade 8 bolts....so we needed grade 8 studs....fine thread on one end....and a certain legnth !...it took all after noon and some of the evening to find them....i was at the point i went to a machine shop and was going to have them made.
yesterday ....with the correct parts. i installed the new coupler (since studs had to be used.....it took a long time to remove the ones i had allready installed and locktited in place....then install the new longer ones)....finally the motor was set in the boat. a hole opened up in the hoist bay shedule..and i swapped bays and had the motor installed and rough aligned in 30 mins !....(im getting good at it)
at this point ....
the motor is sitting in the boat...i am having a heck of a time with one of the big bolts that goes thru the t plate and the flywheel......there is a free floating nut there and i have been 4 hours trying to get it to line up !.
im going back to the shop right now to try and get that bolt aligned.....once thats done....ite just hook ups and installing the elbows.....1 hr max.
if all goes well.......ill flash the motor again tommorow and weather permitting test the new system on the lake....
lol....deja vu.....i seem to remembering typing that statment a few times...
possibly ill have an update tonight after i get home.
cheers
oops
