    3.0 2bbl carb adjustment after rebuild

    Yes I would set the ignition timing, idle mixture ( richen and then lean to a stumble set in middle between those two extremes), then set idle speed screw to like 750 on muffs When you get it in the water and under load you can fine tune the idle. Note you may need to adjust the throttle...

    What size Prop

    Like mentioned the 19" pitch you have would fit the definition of an all-purpose prop. Were you happy with the way it performed? Do you know WOT RPM of that set up? That what you would use to tweak prop pitch of blade configuration. If you don't know that info would just replace what you have...

    Boathouse Length vs Boat Length

    I would be more worried about the boat being centered in the hoist than anything hanging out in the weather. You may need to move the hoist back in the boat house which may or may not be easy depending on how it is framed up

    Vibration at low speed

    I know you said you tried several props, but were any of them balanced? I had a similar issue had the prop balanced at a repair shop and issue went away. Was fine at high speed but I must have bent it at some point kissing bottom

    Wonder if I should go IO again or go OB?

    You mentioned kids, for me it personally comes down to how much you like the swim platform and sun pad. For me and how we use our bowrider those are key and I wouldn't want an OB on the back. For my brothers fishing boat having and empty floor a yamaha 4 stroke works great. The maintenance is...

    3.0 mercruiser ran for 5 min good. Then Just died?

    fuel pump is likely as Chris pointed out, just making the comment to verify there are no up stream blockages that are stooping fuel from getting to the pump.

    Ford 302...21 foot fiberglass with cuddy

    Ok same curve that to me looks like 10 intial plus 24+/-2 centrifugal advance. As long as you have the fuel it was rated for in terms of octane and carb is jetted properly should be fine at 34 total

    Ford 302...21 foot fiberglass with cuddy

    Just found this thread shows total to be about 28 degrees max https://forums.iboats.com/threads/spark-advance-1977-ford-marine-175-hp-302-engine.733308/ not sure i agree with last two posts in thread if graph is total or distributor advance where you would add ten initial to the 24 +/-...

    Ford 302...21 foot fiberglass with cuddy

    Would think that should be ok, definitely safe for keeping detonation at bay Not sure what the stock merc was for that engine. What ever advance limiters were put in there must be limiting it to 14 degrees centrifugal advance.

    3.0 mercruiser ran for 5 min good. Then Just died?

    Mercruiser 3.0 No Spark issues

    I'm not sure if you are using what alldodge posted in post # 21 or the link I sent . In test #2 in what alldodge posted tests coil for short to ground same test is in #1 under ignition coil test in what I posted. If coil has short to ground I would expect no spark. Also as mentioned stick...

    Mercruiser 3.0 No Spark issues

    I would verify that since you have 3 tests not getting any ohms , also I assume coil isn't shorted to ground? You didn't mention that

    Mercruiser 3.0 No Spark issues

    As long as you got a good connection when sticking in terminals b,c,f meter probes may be too fat to get a good connection to the blade terminal inside of there.

    Extended Warranty

    I generally decline them, as I figure the manufacturer wouldn't offer the warranty if they didn't make money on the warranty sale and I am one of the weirdos who actually enjoys working on stuff so I am only looking at potential parts cost. Now if you are the one out of 100 who has a big issue...

    3.0 mercruiser ran for 5 min good. Then Just died?

    I would also check the anti siphon valve in fuel line by tank pick up is opening and flowing, also worth checking fuel pick up tube screen for debris if this hasn't been done. Some pick ups have a somewhat hidden screen in the pick up tube.
