    Alpha 1 Gen 1 Upper Unit Hex Bolt Connecting Halves Broke Off

    if the portion left is up on the surface usually I weld a nut to it and can get it off. Of course this only works if you have access to a mig or tig welder or welding shop. Usually the heat welding it helps loosen it up. if you can thread the nut on whats left and tack it on If you can get...

    Pitch perfect

    you hear hit and miss things about TP (at least from the dock chair experts here...) I have had decent luck with the Vortex 4 blades on my previous boat. they are a good value and for me were a great way to cut my teeth prop selecting with out breaking the bank. The vortex doesnt have a ton of...

    The cowling looks great... Where does the cav plate sit in relation to the water when at speed and the engine pod bottom when fully trimmed in

    How much Prop should i try?

    I did a similar repower went from a 190 hp 4.3 to a 260 hp 5.0 on a sea ray 200 sport. Kept the 1.81 V6 drive . Boat had a 19” vengance on it. Found going up 2” in pitch was roughly equivalent to one step in drive ratio as with a 5.0 my boat would have come with a 1.62 drive witha 5.0. what wot...

    By needle valves do you mean needle and seat that is connected to floats , and have to take the carb top off to get a. or needle valves as in the idle mix screws on base of carb stick up at a 45 deg angle ? if you dump a little gas down carb bores does the engine start briefly? You want to...

    Spray of water from exhaust manifold above O2 sensor

    While you can weld cast iron with tig and the correct rod it is hit and miss And requires preheating and cool down of the part before and after welding. the most honest answer a welder can give you is I will try but make no gauarantee.… it is also double wall. Better way to repair castings is...

    Spray of water from exhaust manifold above O2 sensor

    Probably cracked Looks like a pin hole near. I would dissasemble and use acetone or pressure test to see what's is going on. Are they made of aluminum or cast iron. Aluminum could probably be repaired but cast iron not so much

    bogging down after 5mins

    Additionally you can always run it off a remote tank to verify it is an issue with fuel system supply. As mentioned above that's what it would seem to be. Did it ever run ok with the new carb? often if fuel system is contaminated you will just pollute the new or rebuilt carb.

    Is my gimbal bearing sealed or greaseable

    to me that means the grease holes are not lined up and you are not greasing the bearing. Grease should be coming out around the shielding on the bearing. Run it till it starts making noise then replace it with a permalube or a properly placed greaseable aftermarket bearing. they groan when...

    Pitch perfect

    I might try a different 4 blade than the spitfire. On my 21 ft bow rider I got a ton of slip with the spitfire. It was pretty disappointing compared to the sales schtick. would also verify motor is low enough doesnt sound like it is - do you have a pic of the motor trimmed all the way down

    Have spark and fuel, can't get the rebuilt engine to start

    yes I could see it. it looks good but its a video shot in the dark obvious blueish white spark jumping a good size gap and snaping noise. Seems to be in decent time but also seems battery is weak

    Bellows replacement

    for all I have read about it here and other forums have not had an issue. my family has had a cottage in a shallow cove since the early 60s and the 3 I/O boats we have had have been 33, 25, and 20 years old. the greaseable u-joints in my '91 made it 23 years, the non greaseable in my current...

    Have spark and fuel, can't get the rebuilt engine to start

    more for if the valves are adjusted correctly. Common mistake can be to overtighten nuts on rockers arms, valves don't close. Have also heard that if one intake hangs open can prevent firing but never seen it myself. To the op might be worth checking the rockers on those low cylinder...

    Bellows replacement

    Does seem odd but may be influenced by water quality. I believe in salt or brackish they don't last as long. How were yours torn? My situation being in a shallow cove (drive almost all the way up to get in) and storing on a trailer with the drive up during winter layup puts more strain. The...

    Carter P4389 Doesn't Work when Connected to Carburetor

    Needle and seat in carb is stuck closed or pump is bad. Have you hooked up a pressure gauge to see if it makes pressure vs just pumping into a container ?

    Have spark and fuel, can't get the rebuilt engine to start

    Normally onky seen when timing cover is off. Google degreeing camshaft you likely can tell off the intake centerline. have you run a compression test? See if any cylinders may have valves set too tight. Id do this and verify timing again before taking engine apart. also had a engine with...
