    Motor wont crank..

    Hi all. this weekend I went to take my maiden run on the lake and to my dismay my '79 V175 would not start. The starter engages and fuel is getting to the carbs but it will not "pop off" and run. I took it home and put on the muffs to see if I could get it to run and still no joy. I know that...

    Reverse Lock Issue

    Hi Folks, I've got a 1979 v175 and when I back the boat up in the water the motor rears up towards the boat then slams down once I let off of the throttle. The tilt/trim system works just fine and is one of the old prestolite systems which has the AC motor that sits on top of the rectangular...

    Tilt/Trim issues

    Hello - I've got a '79 V175 that was having an issue with tilt/trim where I'd have to tap the top of the AC motor to get it to run. This sounded like a classic case of it needing new motor brushes so I bought a repair kit (commutator and brushes) and rebuilt it after thoroughly cleaning the old...

    Motor raises up when in reverse

    I've got a 1979 Merc v175 that I recently inherited and recently noticed that when I give it throttle in reverse- the motor starts to rise up and seem to not be "locked" down as it should and then will lower back down as I decrease throttle. Any ideas on why this may be happening? Please help.

    Carb question

    I've got a '79 merc 175HP that i've just rebuilt the carbs on and when i am on the water (under load) it wants to die most times at around half throttle unless i gun it. In speaking to some merc shops here locally the concensus seems to be that there may still be junk in one of the low or mid...

    Full synthetic 2-cycle outboard oil - use it or don't??

    Just wondering if anyone out there has had any experience in using this in an earlier (mine is a '79) outboard and what results you saw with it?

    1979 Mercury v175 dies at half throttle - HELP!

    I just inherited this OB which had sat for several years but has less than 75 hours on it. So far i have removed the 3 year old gas, rebuilt the carbs and fuel pump, replaced fuel lines and the spark plugs. On the water & under a load she will idle great and run good up until the mid-rpm range...
