    Vapor lock or something else?

    Recommend starting by replacing the check valve mentioned in post 4. See what happens. It's an $80 part. Solved my vapor lock problems 700 hours ago.

    Vapor lock or something else?

    I had a similar condition happen on my 5.0 MPI (serial #0M345638). There is a check valve in back of the fuel pump that I believe stops hot engine water from backing up into the fuel pump. The valve had come apart. This fixed mine. If you go to marineengine.com, put in my serial number, go...

    So, my 2025 Bayliner VR5 200 hp 4.5L mercruiser STILL barely pulls me up

    My 19 Vengeance will vibrate around the 1800 to 2000 range also. At that speed the boat is fast dragging trying to get on plane so I never run there anyway. Just power through and get on plane. You seem to be most focused on water sports, specifically slalom skiing. Why has no one mentioned...

    Mercruiser 5.7 MAG MPI Water Pressure Sensor & Oil Pressure Sensor Interchange/Alternatives + 4 in 1 gauge not showing speed and oil pressure

    I know you want things working but I gave up on the pitot tube system years ago. Block the fault and be done with it. Speed is now measured via GPS. Leave the hole on the lower unit clogged it will create less drag.

    Mercruiser 5.7 MAG MPI Water Pressure Sensor & Oil Pressure Sensor Interchange/Alternatives + 4 in 1 gauge not showing speed and oil pressure

    You mean alternatives to OEM? I would buy OEM sensors. Aftermarket is asking for trouble.

    So, my 2025 Bayliner VR5 200 hp 4.5L mercruiser STILL barely pulls me up

    Not sure what they mean by "water in the swim deck". This is not a new boat. It has been manufactured for several years. I highly doubt water is getting in the swim platform somehow. I tend to agree with Pmt. Seems like something is up with your engine. 2025 should be under warranty. Does...

    My boat needs to run real good on the 4th of July. FIX IT !!

    Those still working (at least 4 more weeks) have to go on their day off. I intend to be out there.

    Bilge Pump -Auto or???

    It's beneath your engine. Stick your phone down in there and video to get name/numbers, etc.

    Slip/moored boat what do you do with your trailer?

    I was considering yearly to be frequent.

    Mercruiser alpha 1 gen 2 alarm sounding

    After a hard run he gets an alarm. Remnants of exhaust shutters blocking exhaust passages, BTDT. With the alpha the relief ports on each side of the drive are enough to handle normal running, but not at WOT.

    Mercruiser alpha 1 gen 2 alarm sounding

    Carbed or MPI? A few things to check: Cross check your temp gauge with a IR gun. Point it at the thermostat housing. Is it close in reading vs the gauge? Drain your gear lube enough to empty the bottle. How much gunk is in the bottom of the bottle? Remove and clean if necessary. If MPI is...

    So, my 2025 Bayliner VR5 200 hp 4.5L mercruiser STILL barely pulls me up

    I'm guessing the 19 is the Mercury Black Max. If the 17 was the same I would expect it to put you around 5200 rpms which is 200 over but what you need. This boat is not going to be everything to everyone. On skiing days use the 17 (Black Max), if just cruising use the 19. When going fast...

    So, my 2025 Bayliner VR5 200 hp 4.5L mercruiser STILL barely pulls me up

    You'll need to be more specific with the props. What are the makes, models and steel or aluminum. Hard to believe the 17 only turned 10 more rpms than the 19 unless they are different prop makes or families. 46 mph is moving out and decent performance for this boat.

    Lower unit piece cracked off alpha one

    That's what I would do also. Mine broke off a bigger chunk at the tail end caused by the prop catching debris and pressing against the vent plate. It didn't seem to affect performance but I didn't like the way it looked so I took it to a prop shop and had it fixed. Yours isn't near as noticeable.

    Slip/moored boat what do you do with your trailer?

    All good suggestions. Thanks guys. I'm probably a year away from making a move. Just thinking things through.

    Slip/moored boat what do you do with your trailer?

    Too funny! I tried parking it here when I first remarried (I married into the HOA) and got a nasty letter in no more than about a week. HOA seems pretty strong. My buddy lives in one, in a different town, and all they seem to do is cash a check. Not here.

    Slip/moored boat what do you do with your trailer?

    I was considering yearly to be frequent. Probably no way out of this for me except to keep my current storage for trailer only. What makes it worse is, in addition to the HOA, I live at the apex of a cul-de-sac. So property lines get tight as they approach the street meaning I would have to...

    Slip/moored boat what do you do with your trailer?

    Yeah I'd have to keep my current storage just to keep the trailer. Another 100/month but may be worth it.

    Slip/moored boat what do you do with your trailer?

    Possible maybe. I thought it might fit under my deck but the post to the wall distance is 7'7". Haven't measured the trailer width but I'm thinking that won't work.

    Slip/moored boat what do you do with your trailer?

    It's a 21 foot boat with 8.5 beam. I've thought of something similar but I imagine I would need the trailer more often than I think. Example: How do you remove an outdrive, which needs to be done frequently, with the boat on a lift?
