WH carbs on a 2.5 245

**rjdubiel** · 01-18-2020, 09:59 AM

So I am trying to find a throttle cam for WH carbs on my 245. The original is for the pumper carbs and the roller on the bottom carb is in the complete wrong spot. When I got the powerhead the cam was upside down to make it work with the WH carbs, but this really messes up the timing and sync to the carbs. I was thinking a Bridgeport carb throttle cam may be the one to use. Anyone have this issue before and a solution? May end up making one.

linkage off a 2.4?

I think the carb to carb linkage is what was with the WH carbs, but the cam is the 2.5 pumper carbs cam. I think a 2.4 200 and a 2.4 BP cam is the same?

You can see when I got the powerhead the can is upside downot to make it work with the WH carbs

Will keep that in mind. How much do ya want for it? Would ya send the metal linkage as well? I think the one I have on the 245 is way longer.

Looks like it needs to be flipped ,i have wh linkage stuff will take a look

**rjdubiel** · 01-18-2020, 01:00 PM

The cam does need to be flipped, but the WH roller will be no where close to where the pumper carbs would be. Maybe the pumper carbs roller would fit on a wh carb?

you need all three pieces used on horizontal front carb motor (pre '91), linkage, cam, carb roller that had wh series carbs on it.. anything else ya do whats been done with it before ya got it.. souther'n engineer it!

I'm wit tommy. the rod from a 2.5 is to small to fit in a 2.4 cam , so u will need 2.4 cam, rod ,and prolly throttle arm. The rod link from arm to cam is bigger on a 2.4
I have quite a bit of linkage stuff for 2fo if u need sumthin

**rjdubiel** · 01-19-2020, 09:16 AM

Thanks guys. I have some 2.4 stuff to put on it and will see if I need the throttle arm as well. I think they had 2 different lengths linkage/threaded shaft, 6 inch and 4 1/2 inch. Will let ya know Merc 2.5 if I need anything.

there also may be a difference in tha anchor bracket as well.. think it is tha way tha two adjustment (throttle and shift) barrel nuts are locked inta tha bracket???

Got the linkage all sorted out. Mercury wanted $60 bucks for this part. Could not find any cheap used ones so got the 2.99 round stock at home depot and made one. $60.00!!!!
