OK so if I do replace the lower case I will still have the 1.50....good.
Thanks, pitch is clearly on the side on my other boat so did not look under nut. It is a Michigan Wheel 14.5x17.
I don't know the pitch and can't find it marked on the prop.
Tach and all wiring is new so I trust it to be pretty close.
Where is the ratio set in the drive? at the top bevel gears or the lower? My lower unit is in rough shape and I have a line on a replacement but the sell know nothing about it.
Boat is a 1976 American Boat Company Eagle. HIN says it was delivered with a 351W-233 Mercruiser. At 47 years old the motor and drive have for sure been removed and/or changed.
It now has an aftermarket Edlebrock intake manifold that is stamped Performer 351W, I have installed a new Edlebrock...
All right! Thanks for the extra eyes. I am going to go set the motor to TDC based on the crank pulley and pointer, check that the distributor to pointing to #1 and then order the wires to 1-3-7-2-6-5-4-8 again and see if she'll start.
Okay but in the pic of my boat (yellow wires) #1 is marked with the white grease pencil. Next wire is #3 that is on the same bank as #1 but you can see the wires go to opposite banks.
Maybe that is my whole issue...that mark is 180 off. I just assumed it was the #1 mark since even notes in...
Yep! That was to original wiring that does not even come close to starting. Also that order does not match the picture I took of my engine.
1-3-7-2-6-5-4-8 would mean 1 goes left, 3 goes left, 7 goes right but as can be seen in the pic it is L-R-R....
I know and understand trying to sort this...
Here is a picture I found of a 77 American with 351W. Looks fairly original. Although I can't for sure know which is #1 I marked it based on the routing on my boat of 1L-2R-3R-4L-5R-6L-7L-8R
Some more of what I have looked at:
#1 first wire is marked and goes to left bank based on picture orientation
Second wire goes to right bank
3rd goes to right
4th left
5th right
6th left
7th left
8th right
With 1-4 on left and 5-8 on right not one of these orders will match up.
