    No spark plug spark... 170 MC , 1985 Sea Ray

    could be sloppy dizzy bushings pull the cap, pull the rotor. grab the shaft and wiggle. if the shaft moves more than .007" radially or .020 vertically, pull the distributor and go to napa and spend $10 on two distributor bushings. then put the thing back together, re-gap the points, verify...

    Oh this can't be good. MErcruiser 5.0L loud clicking.

    a brandy new 5.7 longblock GM motor from GM is only $3200. add a new set of manifolds, some gaskets and do the job yourself and your into it for $4500 local machine shop (not your marine guy) could probably rebuild your 5.0 GM motor for about $1500 heck, even if you had to buy new heads from...

    sea wolf construction

    you should have an access cover to inspect the fuel tank. that cover will also give you access to the vent and fill hoses. 28 years is a long time for rubber bits.

    1st time driving from NY to So Fla...route advice needed

    taking 3 days to drive from NY to FL would drive me nuts. Im the type to get in and simply go...... and 20-30 hours later I am at my destination. We routinely drive from Florida to Wisconsin (driving past @redneck joe ) and do it in one trip, with a 2 hour nap at a rest stop along the way...

    Blue smoke during warmup

    compression should be 150 psi. below 125psi you start to loose performance while mercruiser says you should rebuild at 100 psi, I like to rebuild at 125psi. at 80 psi, your motor is toast

    Holley Gurus needed

    So talking to a few of my gearhead friend, they suggested looking at the IFR's. they speculated the IFR on the speedmaster block was way way too small. this is something where very minute changes effect the idle AFR in a serious swing. the Speedmaster/PCE metering block has only .0225"...

    1996 Volvo Penta 7.4 will not stay running

    you are correct, there is no schroeder valve or other test port. it is a diagnostic tool. you need to get a test adapter. such as this one https://www.cpperformance.com/p-62701-fuel-fitting-connector-91-18078.aspx

    Volvo to Mercruiser

    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...

    Volvo to Mercruiser

    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
