    Solas Amita vs OEM (Yamaha)?

    I don't think merc has nearly the amount of selection for the B3 props he mentions, and I think the thread was about AL props so apples and oranges. Certainly Enertia, revolution 4 etc are tough to beat on single prop set ups. My good friend has 24 ft Crownline Deck boat 350 Mag/B3 with the...

    Best Battery for MerCruiser 888 (1976 Ford 302)

    Maybe an acceptable substitute. May just be luck but the batteries have gotten at NAPA seem to hold up well n terms of longevity. The cheaper ones have bought at Walmart or other cheaper auto parts stores, not so much. While a few bucks more might be a better investment

    Bought a Used Boat, but what is it?

    I didn't even consider the OB side as except for small tinnys over the years never owned one. Only asked because my alpha gen one and gen two powered boats have been great for me. Had to read it twice as I didn't know they offered a blender....I get it on the dog clutch, I grew up with them so...

    Bought a Used Boat, but what is it?

    I think you are right, probably more boat builders have gone out of business than are still in business... Its hard enough getting any useful info from the boat builders still in business. Honestly asking - what is the hatred of Merc based on - did you have a bad experience on a past boat?

    Solas Amita vs OEM (Yamaha)?

    if you can get OEM for similar price to aftermarket do so. Might be worth sending your old prop out for repair as a spare. My kids loved the big mable when they were younger. Especially when they were younger had a bunch of kids on it , hanging of the back etc.. I think it lasted about 5-6...

    Stupid question…

    that makes me think the water tube coming up off the pump is not connected. I would pull the drive replace the gasket you mentioned, back flush from the thermostat to the outdrive as the PS cooler could be clogged. Look and see if the water outlet tube is ok in the drive. might verify that...

    Prop damage threshold

    You can try running it and see how much vibration is present. You also can do a static balance pretty easily. I started doing this with my mower blades and it does seem to help keep vibration down.

    Engine replacement help…

    The V6 definitely has less total advance than the V8 modules. Also think the 5.0 has less advance than the 5.7. The 5.7 modules usually also have the knock control piggy backed with it. I have yet to see Kock control on a carbed 4.3 or 5.0 They give less info about the TBV than the older tb4...

    Engine replacement help…

    that’s why you need to swap out the ignition module To match the engine. I test ran my 5.0 with a 4.3 module. On a stand it ran fine. It certainly would not have the correct total advance and not sure if it would think the rpms are higher and kick in the rev limiter. i thought I saw something...

    Engine replacement help…

    If you have a Thunderbolt distributor on your original engine i Am confident the distributor body is the same for V6 and V8. You just need a new cap rotor and trigger wheel, plus a V8 ignition module To use it. Merc ingtion modules are pricey , otherwise use a delco est set up.

    no 4.3 Is great for what it is. Fits the size of boat great, but get the torque of a V8 , you wont even recall the numbers 4 & 3 ..

    Alpha 1 Gen 2 - gear lube in idle relief ports

    pull the drive and see if you see lube. Any gear lube leak the diagnosis is the same, pull drive and pressure test. you may also see some if you pull the prop and look inside exhaust cavity. I just resealed my drive this winter. Wasn’t leaking until I picked up some fishing line on prop seal...

    Alpha 1 Gen 2 - gear lube in idle relief ports

    yes there is not an oring but a lip seal. Looking at the pic on next post the exhaust bellows are above the idle relief pull the drive and see if there is gear oil in exhaust cavity. drain and pressure test the drive

    Alpha 1 Gen 2 - gear lube in idle relief ports

    Is it gear lube and not engine oil or fogging oil? This is the only SWAG I can thinking of -If seal in bottom of upper is leaking into exhaust cavity while drive is in full up position does the elevation work out so it drips into exhaust bellows and day lights at relief holes ?

    Yes it does make it sit lower. I found this in the parts book that came with it, the 5.0's had risers listed as 5.0 w RSR.

    Engine replacement help…

    On mine Sea Ray did not use risers on the 4.3 version , did put a 3" riser on the 5.0 versions so there must be something to it. Going from a 3.7 aluminum block to a 4.3 iron block and heads is probably a similar weight gain. Teething issues aside are you happy with it, I mean none of us are...
