    Trim pump question

    That motor should have the PTT pump/reservoir in the boat. The vent screw has no impact on the PTT pressure. It should be a bit loose to let air in/out of the reservoir. When those systems leak down it can be the control valve or the piston seals in the PTT cylinders. Most often it is the...

    Challenging loading

    There are two speed winches. The "low" gear makes it easy to load heavy boats. They are a lot cheaper than an electric winch.

    Seaswirl throttle removal

    Put the throttle lever in near full reverse, and look for a slot in the throttle arm, at about the 8-9 'o'clock position. There should be an Allen set screw holding the throttle arm on.

    Power Tilt Conversion

    I do not know what to suggest for your question #1. You would need a midsection with a newer PTT unit that still fits your powerhead. They may exist, who knows. As for Question #2: You need a single pole, double throw switch of about 5A, plus one or two solenoids. The PTT pump/reservoir...

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

    I think your boat is a tail dragger. You are not alone, as many are such. It gets worse for larger craft. A lot of boats up to 24 ft boats have SBC power. On those cruisers, you need to send everyone into the bow portion of the boat to get on plane. Once there the boat performs well...

    1979 9.8 Carb Bowl

    I used something similar to seal the gaskets on my fuel tank sender. It seems to hold up. Hopefully you have the same luck. I am concerned about you not being able to find a carb bowl seal that works. Is it possible that you got some old stock (pre-etoh) when you bought the new gaskets? The...

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

    The advantage of hydraulic trim tabs is that if properly installed, when retracted, they are well above the transom/hull point and do not drag. When extended, they will really lift the transom. So, on an underpowered or tail heavy boat, tabs down for takeoff, then pull them up. If heavy seas...

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

    Get hydraulic trim tabs. That will solve your issue, much better than a whale tail.

    You need this stuff, plus the pump/reservoir. The PTT brackets bolt to the upper shock support. The top of the brackets bolt to the top mount of the PTT cylinders. The lower shock mount bolts to the lower mount of the PTT cylinders...

    Gauges recommendation

    SeaRay Gauges are normally made by a commercial gauge company. Sometimes they add the SR emblem to the gauge, but they are usually standard gauge lines. For my '88 SR, I was able to buy standard Teleflex (in those days) replacement gauges. They did not have the SR, but other than that...

    Evinrude Ocean Pro 175 issues

    Gee, be really careful when spraying ether. Have a fire extinguisher handy, as it will likely catch on fire. Using a spray bottle of gas/oil is a lot safer. You probably want a water separating fuel filter mounted in the boat. The dinky strainer on the motor can fill up and restrict fuel...

    Water in the Lower Unit

    It is not necessary to clean out the old lube. Just drain it well. Brake cleaner could harm the seals.

    idle stabilizer or low speed/high speed spark advance module 81 merc 150

    I cannot answer your question, but I know that my '93 Merc V6 idles much better without the idle stabilizer, than my '77 Merc 150HPL6. Deleting it in my situation is not an issue.

    Looking for my first boat and dwelling too much on the I/O vs Outboard question...

    That may be, but my 21 footer has floatation. I would expect many boats up to at least 35 foot have floatation. Maybe more, as the loss of life torts are quite severe.

    Vibration in my Merc 135HPV6 at about 3000PM

    Ladies and gents, I have a vibration in the subject OB at about 3000 RPM. It sounds like reed valves vibrating, but that seems unlikely. The next guess is something on the motor vibrating in sympathy like the partially rusted exhaust pipe cover on my car. The vibration goes away at lower or...

    Evinrude Ocean Pro 175 issues

    That motor, if original alarms, will have alarms for low oil, no oil, overheat and fuel restriction. Low oil in the VRO tank, should be obvious. No oil is an issue with oil being fed to the VRO pump. It could be a clogged filter or broken oil line or a VRO pump malfunction. Overheat...

    Looking for my first boat and dwelling too much on the I/O vs Outboard question...

    I/O engines are mostly obsolete at this point. 4 cycle OBs are a lot lighter, as fuel efficient and have much less maintenance requirements. If you plan the trailer the boat, an OB's light weight makes it much easier. Figure a V6 I/O weighs in at 1100# vs less than 600# for an OB. 2 cycle...
