    92 Mariner EFI 175 Magnum voltage issue

    I've got an issue with voltage issue on an old 92 Mariner Magnum EFI. It is the same as the Mercury Black Max 175. Anything below 2300 RPM and the voltage is erratic, going from 10-14 rapidly. Above 2300, and voltage stays at about 14 v. Any help as to what this issue might be? I have...

    350 Magnum overheating

    Ok, I need help. I have a friend's Celebrity boat with 350 Magnum Alpha One Gen II drive. It overheated on him a few weeks ago. We were talking and I agreed to take a look at it. I found the water circulation pump shot, impeller completely gone, as in spun on hub, and the water pickup tubes...

    350 Magnum overheating

    Hey guys, I have a Dr. friend of mine that bought a 1993 Celebrity 208 boat with a 350 Magnum Mercruiser in it. He is definitely not a boat person. I recommended the boat because I know the history of it and it has always been a great boat for the previous two owners, who, BTW, are boat people...

    1992 Mariner/Mercury EFI Magnum Sync and Link

    I am in the process of doing a sync and link for the first time on my old 92 Mariner Magnum EFI. I've been told it is the exact same engine as a 175 Mercury Black Max. It runs good on top end, but has some idling issues. I have had it for two and half years and have fought these little nuisance...

    Impeller Replacement 175 Mariner EFI Magnum

    Re: Impeller Replacement 175 Mariner EFI Magnum Been meaning to thank you Gerry, but I have been busy boating every chance when not working. LOL! The manual was great! Impeller was a piece of cake. I took it apart several times thinking I had forgotten something! I replaced the whole housing...

    Impeller Replacement 175 Mariner EFI Magnum

    Just ordered the complete impeller kit from Iboats for my Mariner. Best I can tell, it is a 1993. Seems there are a couple of discrepancies in the serial number lookup links I found. Some list it as a 1991, others list it as a 1993. It is on a 1992 boat.LOL I know it was placed on boat after...

    Bimini Top

    Looking to buy a bimini top for my 92 Bayliner Rendezvous 2609. The original top and hardware was lost by previous owner due to the boat being in a boat house on a lift all of it's life. Seems it wouldn't fit in the boat house with the top on so it was removed. The boat stayed in the boat house...

    Setting up an outboard motor on a boat

    I have a question about set up. On one of my small inflatable boats at work, I have a Nissan 9.9 mounted. It is on a small 10' inflatable that can be handled by two firefighters at a scene. It is for a rapid response for ponds we have in the area. I also have a Zodiac FC-470 I set up for rescue...

    92 Mariner 175 EFI Magnum dropped 1000RPM at WOT from normal

    Hey, got a problem I can't seem to figure out. Last Sunday, the boat was running good. About 5500 RPM at WOT, 39-40 MPH. Ran it for about 3 miles. Parked at the sandbar for a couple of hours. Left the sandbar, opened the throttle and it had a stiff spot in the throttle lever at around 75%. I...

    Removing 3M 4200 from hands?

    Resealed all thru-hull transom fittings today with 4200. I started out using gloves, but they started tearing and getting sticky so I pulled them off. Wound up getting this stuff all over my hands. Tried mineral spirits but I guess I let some of it cure on my hands. How in the world do you get...

    Looking at buying a 2012 Sea Ray Sundeck 200 for 40K out the door

    Re: Looking at buying a 2012 Sea Ray Sundeck 200 for 40K out the door My suggestion, get what you really want. The layout on that boat is going to be very cramped for 5 soon to be grown people. I can guarantee you are going to want more room. Get a deck boat even if you have to back up a...

    Have a few questions about a boat engine I just bought. It is on a 1992 Bayliner Rendezvous that has been stored in a boat house for last 10 years. It is a 92 Mariner EFI Magnum. The motor starts fine if you throttle up to about 1/4 throttle when starting. However, when you bring the throttle...

    1992 Bayliner Rendezvous

    Just purchased a 1992 Bayliner Rendezvous for the family. This is an old deckboat catamaran. Seems to be in really good shape. Spent 10 years on a lift inside a lake boat house without being used. It has since had the fuel system overhauled and a few other things replaced to get it back to...
