    3.0 GS - Overheat followed by power steering pump belt snap

    They would’ve had to have taken the power steering belt off to change the alternator belt so they probably didn’t tighten it up enough

    Rochester 2 jet running rich before and after rebuild

    What your fuel pressure?i assume you mean the vent for the fuel bowl? There is no vent for power piston you can see, it gets pulled up by manifold vacuum. If you see fuel on the top of float bowl your fuel pressure is too high overcoming the needle and seat, or the needle and seat/ float...

    Alpha One Gen 2 impeller delete question

    This is the correct way to install a fresh water system on an alpha. to the OP before you hang anyone, look and see if there is room, and if that will be any easier to change. Some of the comments folks have made about the contortions they need to do to change a belt or crank pump makes me...

    Water in Engine

    Agree with ted i would be verifying there are no leaks On exhuast manifolds elbows and risers . I would think based off your comments it hydro locked while they were swimming. other thing pressure test cooling system if you dont find issue with exhaust. now that you have it running make sure...

    Oil change on TKS 3.0.

    when I repowered. I changed the oil after 1 hr, then at 10 hrs, then at end of season per my normal routine. Maybe be over kill but oil changes are cheap and you can see if metal particles are in the oil

    Volvo Penta SX Prop ID

    Yeah i know you dont like 4 blades…. both the enertia and rev 4 played very well at high trim levels , if i recall the enertia could trim almost all the way up. the rev 4 as you are going faster you can keep adding trim up, if you slow down and are still trimmed out and then punch it it will...

    Volvo Penta SX Prop ID

    Any time. the key is to match your boat and how you like to use it to a prop. I forgot you are running a 21 now not a 19" so likely 20" 4 blade would be ok. I think the props will fit but you might need a different hub kit or thrust washer , would really depend on the prop. Best bet to get the...

    Volvo Penta SX Prop ID

    Yes and no... First time I used a 4 blade (old boat- '91 17 ft Sea ray 170/3.0L) Went from 17" or 19" (skiing/Cruising) Black Max to a 16" or 18" (again skiing or cruising) Michigan Vortex 4 blade (aluminum). Lower pitch ski props aside, Boat was better in every performance parameter except top...

    Prop advice needed

    Fix your tach or verify correct WOT before playing with props. Obviously 19" is too much pitch and you are lugging the engine. If 4400 was indeed accurate you should be going down in pitch not up A 4 blade will help with stern lift, hole shot, and lower planning speed. Props are trade offs if...

    Volvo Penta SX Prop ID

    If those are accurate you are propped correctly. I think the VP ss props are fairly decent. I personally prefer 4 blades as loaded watersports is my typical use , i would drop down in pitch if you go four blade nothing wrong with being bale to tap the rev limiter lightly loaded, better off...

    Mercruiser 3.0 No Spark issues

    given that you suspect a rotten transom and you have been flex testing it by jumping up and down i suspect you have your answer… i would be drill testing the transom if you haven’t. Hard to tell from the keyboard how bad it is

    Mercruiser 3.0 - Electric and starting problems

    Ricks right start with some basic maintenance. Likely you have ab electrical problem possibly related to the second battery and switch, which may have not been installed correctly. When it died on the water it tripped the 50 amp breaker which kills power to the engine and the helm. There is...

    2002 Four Winns 248 Vista with Volvo Penta 5.0 GXI

    In my area nada reports low retail at $21k, high retail at $24k. Boat prices are high now so depending on how much effort you want to invest in it I would think you could be quite a bit higher than $13k

    Need Assistance to Diagnose Bravo 3 - 5.0L MPI Vibration

    Jam a hose in the water port on the bellhousing where drive goes on. I think cutting an old washing machine hose in half works well. Doesn't need to be 100% water tight

    454 Low Vacuum + Flutter?

    Yes it should be higher 17-20 ish. Have you done a compression or leakdown test? Wondering if a valve is hanging up or if you have an intake or carb base gasket leak. If you had worn valve guides I would expect oil smoke on start up and oil fouling on spark plugs
