    5.7V8 with a 1.84 alpha one gear ratio

    I would start with 4” more pitch than what was on there, 23” if you dont know. Would second to start with an aluminum until you rough it in, unless a prop shop will let you try a bunch. I think you have an advantage here In That a 23 ft is a fairly large boat for a 5.7 to push so the steeper...

    Tahoe q7i prop

    The ignition module has a rev limiter in it so you can’t overdo it

    Tahoe q7i prop

    I think typically a 5.0 carb engine will have a 1.62 ratio in this size boat.

    1998 Volvo Penta 4.3L GL

    I did the same swap in my searay 200. The side motor mounts and front of the engine are 4” farther forward. My boat was set up with motor mount stringers that accepted either the 4.3 or 5.0. So as long as you have room in front it would be worth it.I wouldn’t bother if you have to move the rear...

    Stainless Steele or NO..

    Pfopbably not worth the money. Are you looking to correct any performance issues besides the fact that its a pontoon boat?

    Try an enertia they aren’t cheap but generally hear good results on them.good balance between acceleration and top end, good bite when trimmed out.

    Blessing in disguise

    You may have to step up in Prop pitch I’d run it and see. I swapped a 4.3 for a 5.0 and kept the steeper 6 cyl drive ratio went from 19” to 21” pitch and it works perfectly for the valve seal and piston and ring questions I’d talk with your machinist who will be doing the work on this. new head...

    5.7 Venturi Cluster

    ok now I see what you mean. I don’t have a mercarb handy but does seem really odd.if you can’t find one there are a number of YouTube vids rebuilding these carbs or call a carb shop like mikes carb parts and ask. I would not Think you would want to solder it shut as it looks unmolsted , you...

    5.7 Venturi Cluster

    Which carb did you buy specifically from whom, I think Sierra does make a merc a knock off that is new, likely other sources are remanufactured carbs that may have a mix of parts if some one made a mistake during rebuild

    No Spark

    Also check man overboard switch should be red toggle switch on throttle control. This cuts off power to ignition circuit

    1997 5.7 Gi fuel system

    in addition to Lou s comments about cold starts - its seems like your engine had fuel injection on it, then someone hit a roadblock parts or maintenance wise and swapped out for a carb? Must have been problematic enough to tear it out? i have a1409 on my mercruiser 5.0 that works very well...

    19' to 21' Bowriders or Sport Decks

    I’ve been very happy with the two Sea Rays I’ve owned over the last 25 years- 1991 170, and a 2004 200 sport. 21 is a good size for that lake And uses you outline. Look at the SPX 21. personally I prefer IO ,despite the advantages of a modern 4 stroke ,solely for the a clean swim platform on the...

    Changing Gear Ratio...Prop Change Required

    Yes try the 21” check wot rpms. You may over rev so back off the throttle when you get to 4600. going to steeper gearing will improve ( all other things being the same) holeshot and will limit top end, hence going up in pitch to compensate. Five years ago i swapped a 5.0 for the original 4.3 in...

    Hull stringer material

    That weekender is much different in terms of construction than my ‘04 200 sport. Not the best photo of stringers as I was just getting done repose rings , but the stringers and floor are smooth and shiny just like the hull. I think this model and hull design was released in 04.

    Hull stringer material

    True wood was main material used for stringers transom and deck material for many years, often nothing more than plywood tabbed in. Around the early 2000s manufacturers started to transition to more modern materials. I suspect driven partially by ways to reduce assembly labor. If you compare how...

    Hull stringer material

    My 2004 Sea Ray does not have wood stringers I believe they are composite and ‘glued’ to the fiberglass hull look around the engine mounting points there will be 1” plugs in the side of the stringer for putting foam under the floor you can easily pull one out and see the stringer construction...

    MC1 Gimbal with Alpha Gen 1

    Alpha gen one will fit a mc1 transom assembly so that is a common maintenance swap out over the years. Im not sure if they swap put if you google mercruiser 32582 you’ll find some used steering pins. your best bet if you can find a rotten boat sitting in someone’s yard is to get a complete...

    Vortec or not?

    O this won’t work . I’m assuming since you mention 4 bbl set up you are looking at swapping the intake and carb onto your 99 2 bbl engine? No the intake will not fit your later vortex heads, as outlined count the intake bolts.
