Need some advice Please
my omc is 990245S1 andit would not go into reverse now more. So I went to a shop for help and wastold to fine a full mechanical shift 400 as it would be better then the hydromechanical one I have
So $1000.00 later a model 983486 was told this is a 400 and it came with shiftcable and control box with broken mounts!
Yep I started digging into it when I drained the oil's to put new oil in andfound water in the case, so ok at this point put in a new water pump new ballgear and seals and O-rings do the job right and maybe not have any problems!???
Well at the water pump
Ok I am stumped here the unit I got model 983486 and 86 being the model yearright????
this unit I have looks just like my 79 400 parts and all inside and it lookslike this
https://www.*****************/parts/o...Gearcase+Group
it is not this unit !!!!!
https://www.*****************/parts/o...r+Gear+Housing
So at the water pump
I have done this job twice on my omc 400
I get the pump out and #35 — 909753 — DRIVESHAFT is like stuck / welded/ frozen to #47 — 909121 — DRIVESHAFT, UPPER I have beat this with ahammer I have heated it up and tried to us a press nothing !!!! the two WILLNOT separate!!!!
so my question here will be can I use my water pump unit from my 1979 unit andinstall it in this unit it all looks to same
but the new unit has a aftermarket heavy duty water pump kit and I thinksomeone used Loctite or something like it on this shaft
#51 — 910240 — BEARING HOUSING
the 1979 shows the same #51 — 910240 — BEARING HOUSING
the gears are the same and all 0982476 - L/P 1495.00 1985 and 0982476 - L/P 1495.00 1979 both years are the sameunits
Over all this new used unit I have from marineengines.com
from there pictures of the unit there the unit I got fits in the 1984 modelyear but still the same part numbers over all
