    1986 Mercruiser 470/170hp/3.7L Carb backfire, low vacuum, other weird issues

    normally those are a tight fit between baseplate and throttle shaft. When restoring carbs some better rebuilders will bush the throttle shaft to seal. On a new carb this should not be send it back and rebuild the oem carb or have it rebuilt by someone competent. This is the rub with these...

    Buying an '03 Sea Ray Sundeck 220

    The block is cracked- Doesn't matter what oil pressure is. Pull the engine get a new long block and manifolds. I did a similar repower on a 04 Sea Ray back in 2016. I ended up getting a new (not reman) extended base engine from Michigan Motorz. of course it was more money this way but just...

    Would think there was insulation there originally. When mine started flaking off in the wind I got material from these guys-...

    Need Help Selecting New Trailer Brake Kit/Actuator

    I put that kit on my trailer back in 2015- dual axle Magic Tilt - just under 5k total weight. I don't tow that far or that often, only had one issue where I pulled the boat at end of season and the pads were rusted to the rotors (trailer sits outside during summer) , so good thing they switched...

    installing a remote oil filter set up, got a question....

    I think we had a thread on this.... What bypass are VP and Merc using in their OEM setup? if there was an issue with that someone would know, would also think MM would know as well.

    40 HP Johnson, just tilt or tilt/trim?

    I would think if they are calling it tilt and trim then yes you can trim with it. There was a note on the parts page you listed Power Trim/Tilt "F" Model Number Suffix Only do you have that in your model number?

    installing a remote oil filter set up, got a question....

    That one has swaged hoses essentially same material as hydraulic hoses vs some of the cheap automotive ones with hose clamps... Would think the hoses are good for 10-15 years would just keep an eye on where you run it and if they are chaffing wrap them so they don't abrade

    installing a remote oil filter set up, got a question....

    Its only to keep excess tape out of the fuel or oil system keep them off the end of the fitting you are fine or use teflon paste. I suspect you know not to use them on the flare fittings shown. Assume there are some NPT threads in the system? On a tapered thread the thread makes the seal the...

    Can’t Figure out Prop ….

    Check what is on there now not the catalog, 23 doesn’t seem correct As my 3.0 was sluggish with a 19”…and we keep asking current wot rpm. This is key to deciding next prop. Do not try a different prop without establishing current wot rpm.

    Oil leak - Volvo Penta 5.7

    Seems like you need to be looking for a ps leak if you are loosing level every few weeks. Would look at return line clamps going to ps cooler

    Can’t Figure out Prop ….

    Cant read the numbers from here. You need to pull it off and wire brush the numbers- are there any numbers on the side of prop? Looks like it hasn't been off in a while? if so might be good to grease the splines and check the annode behind the prop. As Scott outlines need to know your current...

    1986 Mercruiser 470/170hp/3.7L Carb backfire, low vacuum, other weird issues

    that is not how a power valve on a rochester 2 jet or Mercarb works. There is an piston/actuator that comes down from the airhorn and pushes the power valve open. At high vacuum/low throttle opening the piston gets pulled up into the airhorn and doesnt push the plunger on power valve open...

    not needed you are pushing against plenty of metal. What are you using to weld with tig or mig? Was trying to guess from the photos.not mocking your work, I’m just learning how to tig aluminum .

    Merc 3.0 Overheating

    Have you verified the 175 plus is accurate with an ir thermometer? Do you have a ps cooler Is it clear of debris. There is a test to verify water flow up to engine I think you want to see 3 qts in about 15 seconds .

    1986 Mercruiser 470/170hp/3.7L Carb backfire, low vacuum, other weird issues

    Jets do not affect idle and transition circuit . If you look down the bore and see when fuel starts dropping off the boosters you will be close to 2000 rpm, below that you are on the idle circuit

    Really Dumb Lower Shift Cable question

    save yourself a hassle and get an OEM one. If you pull the core out of the old one, shove a weed wacker wire back up it, tie it off in engine compartment, slide old sheath out, then use the weedwacker wire to route it properly around the wye pipe etc.

    Which hull brands to avoid

    Agree on the Bayliner, most of the really negative comments are old thinking. The newer ones are very close in fit and finish to the Sea Rays they are made next to in the same plant... Also agree on used stuff how it was cared for and maintained is more important than anything else.

    Pistons on Ford 302 / Mercruiser 188

    I don't think prior to the Q-jet coming out they had a 4 bbl big enough in an OEM format. The AFB that was on the early 4 bbl engines is 500 cfm. I don't think the 3x2 had better mixing than the 4's. I think in the end there is a reason that Pontiac went to a higher rise intake and the q jet...

    Pistons on Ford 302 / Mercruiser 188

    Never saw the movie. That is the original color Burgundy, just the cross ref number PPG gave me when I painted it back in 1992 is a touch more red, actually like it better. Rust wasn't too bad on this but accident damage was and the engine trans and diff had been blown up at various times. I...
