Can you swap a 1999 mercury 150 xr6 powerhead with a 1999 force 120

[Hazen91]

Hi I was wandering if you can you swap a 1999 mercury 150 xr6 powerhead with a 1999 force 120 with out much interference. I know it’s a down grade but the 150 has a bad piston and this would be a cheap way for me to get the boat back in the water. Any help would be appreciated.

Well----I don't think so if you are thinking of swapping just the powerheads. -------A 4 cylinder inline 120 and a 150 V-6 are totally different.----Not even close.----Swap out the whole motor maybe.

nothin' "force" will interchange with production V6 merc/mariner....

you can unbolt the mercury in its entirety, then bolt on the force. however you may need to swap controls as well. however you can not swap parts.

I think the controls will work, since Force was owned by Mercury in that time. They will need reversed but the control should have the provision..

If you happen to find a "Mariner" v6 powerhead it's likely that will work though

Compare the gaskets. There's your answer.

a Force powerhead WILL NOT bolt up to anything V6 Merc/mariner.... a Merc/mariner V6 powerhead WILL NOT bolt to any thing Force....

How about the splines in the crank, I highly doubt they match

Wont even fit......don't waste yer time looking at gaskets and such.
