I run across 73 pintos when looking for old cars, doesnt mean they are worth buying...... I mention that because it would be more work and potentially more cost to buy an obsolete motor that you cant get parts for vs the current obsolete motor you have that you cant get parts for. you would...

why are you enamored with obsolete motors and drives? just curious. the volvo AQ120B has many NLA parts you would be better off finding a 290DP or a DP-A drive with a V6 or V8 that is 20 years+ newer

have you checked to make sure the battery has power? is the battery connected?

the new 4.3 is LS based. still GM, https://gmpowertrain.com/products/lv1-engine/

no, those pics are out of focus.

Check fuel pressure If you have a crab cap, change it Generally a lean sneeze on accelerating is running out of fuel

of all the damage, this is the only one that I am concerned about it looks like it may be a prior repair and you have water dripping from the gouge the rest of them can be filled with thickened gel simply start with 80 grit sand paper, clean the gouges really well, build up with thickened...

what color are the decals? Blue? that would be 1982-1983, or Brown 1984-1985. my guess is you have a 1985 since the serial numbers for 1985 start with 6611886 and go up to A196291 these exploded views may help...

Ted, yours appears to be the earlier cowling. Mine were 1985 motors. @Dinglydel what year is your 7.5?

I prefer having the area open underneath and making sure you dont get water in the bilge to begin with.

change your impeller. running for just a few seconds without water will toast an impeller

bayliner did side mount 3.0's at the same spacing / location as 4.3's so they could drop in either a 4.3 or a 3.0 into the same boats.

By the way, the instructions shown are wrong, it says to turn counterclockwise and should read clockwise. note the location of the spring arm pivot to the idler bearing center, it can only turn clockwise to release

you didnt get all the paperwork then. in addition to the bill of sale, you need the signed title and/or signed registration the DMV/DNR/AHJ whatever you have that registers boats in your area will only need the BOS and signed title and/or registration. you may have an issue trying to...

remember, a jet boat motor is hard mounted to the pump housing. different animal for mounting. cant compare at all.

you are turning the bolt the wrong way you turned counterclockwise vs clockwise, all you did was remove the bolt holding the idler on the spring loaded arm. do not run like that, it will walk that idler off its post and fling it at your head. now put the bolt back in and turn clockwise, and...
