1968 evinrude 9.5 hp gear box question

[hungry hunter]

my father told me that he thinks he switched the reverse gear and the forward gear around when he put new seals in the the gearbox because the forward gear looked a little worn but he can"t remember for sure if it was in this motor or another 25hp motor he had. if anyone is familiar with this particular motor is it possible to do this or are the gears differnet? I was looking at a schematic and it shows different part numbers for the two gears but I would like to know if they could be switched thus causing the forward gear to be slower and the reverse faster? or is he recolecting a different motor all together. any help is appreciated

As far as a worn gear goes, my suggestion is to just buy a new gear and seals and install it now. Parts are available online and are not really that pricey.

My 2 cents worth

I am pretty sure that they are 2 different types one is spun x direction and the other y. I am trying to remeber back when I tore apart my 69' 25 hp.

Going from memory from when I had my old Rude apart I'd have to say it shouldn't matter. I think both gears are engaged at all times by the bevel gear (looks like 38 on your schematic). Direction is dictated by the sliding block on the prop shaft. If the gears are different they wouldn't mesh.

Mitch is correct, both gears are always in contact with the bevel gear on the end of the drive shaft ... and they are always turning. Forward or reverse movement is controlled by the position of the clutch dogs in relation to each gear.

That said, if I recall correctly, on that lower the bearing surfaces are different on the forward and reverse gears. If I am correct (loaned my book out) the two gears could not be switched.

What I have done in the past (never tried it on this lower) was to reverse the clutch. Often you will see wear on the forward dogs of the clutch and the reverse side will look like new. Makes sense as we don't often drive the boat in reverse ... compared to forward. On some models I ahve worked on this clutch could go in place either way ... so I flipped it around 180 degrees, which moved the dogs with minimal wear from the reverse side to the forward side. Maybe this is what your father was thinking.

Also, if the gears can be switched on this lower ... I'm sure they are the same size. So, even if reversed the speed reduction through the gears would be the same for both.

hope this helps

This very well could be what he was thinking,Im pretty sure that can be done on this motor
