    How much should extra weight slow me down?

    Vortec, 4bbl. Should be 50hp, but 200# weight hit. I'll be probably getting a 4 blade prop at some point and will likely drop, but I'm pretty much where I should be most of the time. Still 4600 with 3-4 on board. I still haven't had a chance to see how it pulls me on a slalom ski...

    4.3l engine questions

    And if you feel like buying used, in my neck of the woods they are literally $15 at the pull a part.

    How much should extra weight slow me down?

    Just curious. Still haven't gotten the performance I expected after my 3.7l --> 4.3l upgrade. It's a touch faster on the top with better mid range. Me + full tank gets me 48-49 mph @ 46-4700 rpm. Today out with about 1000# extra people/gear (6 real people, 2 kids) and topped out at 42 mph @ 4300...

    2005 regal commodore 2750 stringer/transom material?

    Got a buddy with the above boat. Apparently it started leaking. He's not sure where it's leaking from, but he does not think it's coming from bellows. Thinks it might be around drain plug. I'm thinking this sounds like a rotten transom, but am hoping for his sake that it and stringers are...

    Running my boat on Land

    In all fairness the op doesn't seem to know what they're dealing with... So hard to know what to search for.

    4.3l engine questions

    Your mid range will be night and day vs. the 3.0. my 4.3 doesn't seem much faster than the 3.7 I replaced, but everything in between is effortless with no drama. Tops out at 48-49 still, but 40 is much easier. Still waiting to ski off the damn thing, very curious as to whether it pulls harder...

    Gimbal Bearing Noise?

    That isn't at all true. Ignition and fuel for the most part, but there are *many* auto parts that can be used on a boat. Op, pretty damn tough to bend a yoke. How do you know yours is bent/how did that happen

    Shift Cable Issues= Alpha One Gen1

    Did you check out the shift cavity of the drive? Sometimes it can fill up with schmutz and keep the slide from moving forward into the cavity.

    1983 thundercraft live well pump?

    Yeah, those look like single throw replacement switches. The original nav/anchor switch was 2 position. The red/green should also turn on the white stern light. Anchor turns on the stern light only. Depending on how creative the wiring is, 1 of the switches is for anchor and 1 is for navigation...

    Mercruiser 4.3L Thunderbolt 5 engine age

    I mean, the obvious question should be why are you looking at a 4.3 in that boat? Plenty of room for a V8...

    What was mounted here?

    Those look like mine. There's a wing-nut type insert with a hole in the middle that screws into the bushing. Apparently the idea is to unscrew a bit, let it drain until it clogs, and then replace the block in the spring :rolleyes:

    TKS & diode & fuse

    Yeah, seems like a real rube goldberg system. It will run without the diode, forget if it will run too rich or lean. The diode keeps the tks from backfeeding the ignition. @alldodge has some very good explanations and diagrams of the system, not sure which of his posts is most up to date/complete

    Ha, which one?

    Missing timing tab? Merc 4.3 2005

    How confusing. Marks to the right on the damper are BTDC, marks on the left of the pointer on the timing cover are BTDC (which you don't have). Depends on your reference. Your timing tape has BTDC on the right when referenced against the stationary TDC mark on the cover

    Mercruiser 3.0 squeal keeping engine from starting

    I still think you need to turn it over by hand to feel where it's binding. I doubt oil treatment would make any difference. Running without load on the engine might. I'd be surprised if there really isn't a way to access the damper enough to turn it over, but I don't have experience with the 3.0

    ignition switch source for fuel pump relay kit?

    Looks like it, I can't tell for certain without seeing the whole thing. Should have 4 terminals,2 yellow black wires. It's just a relay that drives the starter. Sounds good.

    ignition switch source for fuel pump relay kit?

    You aren't. That 12v only is used to trigger the relay, which draws very little current. With the relay all of the current goes from your fat short red wire through the relay, on to your fat short wire from the relay through to the pump. None of it (pretty much) goes through the switch.

    5.7l mercruiser gen 1 alpha 1 to vortec head swap problem please help...

    @Lou C could probably help you out as well. Don't know what happened with the carbs and jetting between the vortec and non v8s. The 4.3 for sure needs to run fatter with the vortec
