    Oil Pressure Sender failure modes?

    yeah always watching OP and temp. Had an over heat last summer due to weeds on outdrive... had been towing my daughter skiing then picked her up took off through some weeds and it went from zero to alarm going off in an instant

    Oil Pressure Sender failure modes?

    you must be bored or out of beer... looks like the thing works now so leave it alone. Seriously though I converted my factory gauge on my 65 GTO (was 0-60 psi) bc my engine makes about 80 psi and gauge was always pegged above idle. I was able to find a 0-80 or 90 psi sender that had same ohm...

    No Trailer and Trim Up

    your description makes sense, but the switch being NO is opposite of way you would think it would work... would think its NC until bellhousing hits it ... I would just jumper it out so the trim up works all the time. keep it simple and if you pay attention driving it its no issue.

    Bravo 1 to Bravo 3 Conversion

    if 6 ppl plane out time was good you are probably in the ballpark. Will be lucky $$$ if you can run the same props.

    Main Jet size for carb 7043183?

    As Ad points out I have seen it for some carbs in the carb section of manual or some addendums, but not for anything that old. I think I saw one for high altitude jetting but again not for a 165 engine. if you can verify the size by getting a NOS jet may be best. if the plugs look good may...

    No Trailer and Trim Up

    Do you have a wiring diagram for your set up? I know the earlier ones are a bit more complicated... If i recall you have the three button switch where you have to press the upper two to get all the way up? I suspect what ever limits the trim up is bad as well as the switch you just jumpered...

    Main Jet size for carb 7043183?

    Sometimes you see them in the carb tune up specs in the factory manual but a quick search I cant find it either... How do the plugs look? these guys seem to have one NOS jet with PN AD listed for sale. Could buy it for less than $10 and cross check...

    Some early ones did not have a lube bottle.

    salt water in single cylinder

    It will have a mercrusier serial number tag riveted by the starter Mercuriser buys gm base engines/ long block and builds them out so it is just a gm truck engine with minor tweaks

    salt water in single cylinder

    090M is for metric. For some reason they used metric fasteners on some of the 4.3 blocks... in true GM fashion only some of the threads are metric- starter bolts, flywheel cover, and front/side motor mounts. I bought about $40 worth of SAE bolts to convert when I did my repower. If you are...

    Cant start engine when opening throttle. Mercruiser 3.0

    yes you can jumper around the neutral safety switch , but remember its there for a reason. May be an issue with the controller and not the switch. I would look at the shift plate and see if it is going in gear despite pushing the button in.

    aluminum prop comparison

    Based on that feel I would go up 2" in pitch would probably get you there but you might loose holeshot and pulling ability some. you could also have cup added to your current prop

    Running temp for 3.0 tks mercruiser suntracker 27 ft pontoon?

    I would fatten up the idle mix a tad, and make sure idle speed is down. Was the old carb running rich ? if so maybe need to remove carbon from inside combustion chambers with sea foam or GM top engine cleaner

    aluminum prop comparison

    I think he still has throttle to go when he hits the limiter limiter is normally 5100 or so maybe a touch higher for MPI

    Let's talk skill...

    yes and likely you are overcorrecting try very small steering in puts, and there is a lag in steering response when OD is trimmed way up on the jumping when it goes into gear would be you have an issue with shift cable dragging. While the alpha dog clutch does require brisk shifting to pop into...

    Oil Pressure Sender failure modes?

    I would suspect you have a ground issue between gauge and the block maybe at cannon plug. Not sure if power supply to gauge or voltage drop to gauge will do it... as mentioned put a mechanical gauge on a T run it so you know there is oil pressure in the engine.

    Thermostat/temp

    No with a 160 stat the engines run about 170-175 so what you see is completely normal . My 5.0 with same stat runs the same temp.

    Popped through the intake.

    Agreed the webber edlebrock is easy to tune if you have some background in it. If you have the factory webber put that on and see if the issue goes away. The rochester with one idle jet (screw?) is a mercarb. Merc made their own after GM stopped making 2 jets in late 80's or 1990 ish. Obviously...
