I'm still up in the air about Johnson pump or the Merc/Jabsco pump.
Thanks

Nice pics mo' I have the same set up on mine..Impeller swaps are a snap.
Don't forget Mako, you can rotate them any way you want so long as you get the anti rotation bracket on & it fits, so it offers some flexibility.
As for the alpha, I know it pushes water.....are you planning on leaving the impeller in there. I'm not sure how good the water can be sucked through it ?
Never thought of that, I them with bravo's
Anyone know ?

A while ago I asked the question about converting an Alpha drive to an engine mounted pump. I was told to use an external water pickup but keep the impellor in the drive and use it to supply a drive shower. The Alpha is dependant on the water flowing through to help cool the drive oil.

Thanks for all the input. Very nice work, I noticed you keep an extra "V" belt back there within the bracket "just in case." I purchased the Johnson pump and installed about a week ago, have since removed it when I ran into the bracket issue. According to I-netmarine.com the only brackets made were for a 2 belt pulley, that's when I removed the pump and was going to go with the Merc pump.
Your setup is the way to go, any concerns on loading the pump bearings when bending the bracket to fit (the 3 belt pulley). I was thinking of adding back stock to the bracket, equal to the 3rd V groove on the pulley, or even a simple spacer to make up the distance.
I also purchased a set of bronze bushings 3/8" x 1/2" x 1/2" for about $1.50
Thanks, if you think of anything else, please let me know.
Regards,
Scott
PS,: I will keep the impeller in the alpha for outdrive cooling. I was thinking of simply moving the oil cooler water supply line, to an existing "above the water line" thru fitting. This way should something go wrong I still have that supply.
Have installed a 1 1/4" scoop thru hull with sea cock for new supply
