    Flooded Engine

    What is the best way to start my 454 MPI flooded engine? My engines ran perfectly all day and when I got home, where the engine sat for about 45 minutes, it would not fire up when I went to flush it out. It actually would fire up for about 2 to 3 seconds and then die. After about 6 or 7 fire and...

    New Exhaust

    I just picked up two sets of exhaust manifolds and risers for my 454 MerCruiser engines. I have a question concerning the gaskets that go between the exhaust manifold and riser. There are two kinds of gaskets. I am not sure what gasket to use for my exhaust. One set has some of the water...

    Steering Replacement

    Last fall I had my boat in for repair at one of our local marinas. There was excessive play in the steering wheel of about 2 inches. If my wheel was at the 12 o'clock position you could turn it and it would not show any resistance until either you hit the 10 o'clock position or all the way to...

    Mercruiser Leak Down Test

    I am still experiencing hard starting on both of my Mercruiser 7.4 MPI engines after they have been shut off for about three hours on the water. Someone suggested I do a leak down test on the fuel pressure system. Does anyone know, once I attach the gauge to my schrader valve on my fuel rail...

    Oil Extractor

    This fall I plan on changing my engine oil. Does anyone have a recommendation for a good quality oil extraction system that would screw onto my dip stick threaded connection on the engine. Would I be better with an electric pump or going with a manual pump? Thanks

    Trim Indicators

    Both of my trim gauges are not working but my trim controls are working perfectly. Both the starboard and port gauges indicate both drives are fully up and don't move at all when I either lower or raise both drives. My port gauge did work but to try and transfere the problem I just switched out...

    Out Drive Trim Indicators

    One of my drive trim indicators was not working although the drive was moving up and down.I decided to just switch trim indicators and see if the problem transferred to the other trim indicator. Once I did this both trim indicators are indicating both drives are all the way up but actually both...

    Exhaust Manifolds

    Looks like sooner than I expected, I will be replacing both motors exhaust manifolds and risers. Can someone chime in the pros and cons of going with aluminum manifolds vs the cast iron manifolds. I am seeing aluminum ones on line for about $250 a side.

    Remanufactured Engine

    A while back I had to replace the starter on my starboard engine. What caught my eye was the serial number plate right above the starter. This number did not match up to the number on top of my motor. The serial number plate plate states that this engine is a Quicksilver re-manufactured engine...

    Port Engine Running Hot

    Over the weekend I was able to replace the raw water pump along with the thermostat housing and thermostat on my starboard engine. This engine was running between 190 to 200 degrees before the change. It now is running between 150 and 160 degrees. Now on to the port engine which also is running...

    New Raw Water Pump

    My new raw water pump arrived and I am about to mount it to the bracket the old one was mounted. What I did not do is watch for the orientation of the pump to the bracket on the old one which has been removed from the bracket. I understand, if I do not mount it correctly such as upside down, it...

    Water Pump Leaking

    On my starboard engine the raw water pump is leaking between the pulley and the housing on my 1999 454 big block. After struggling for over an hour I was finally able to remove it from the boat. Can't understand why a boat manufacturer would design the back seat to be within an inch or two of...

    No Start Condition

    Went out Sunday for Father's Day in Tampa Bay. Boat behaved nicely throughout the day. We decided to take a ride over to the other side of the bay to have some food. We shut off the boat and when we got back from eating both motors turned over and fired up for about 2 to 3 seconds and then...

    New Trailer

    After giving it a lot of thought over the last 6 months I have decided to go with a new trailer for my 29 foot Powerquest. I was originally going to upgrade my 7,000 trailer by going with 5.200 pound axles, new 12,500 pound actualor and 16 inch tires. It turned out because of a trade in of my...

    Both Engines running hot

    We were out over the weekend and encountered both engines running near 180 to 190 degrees which I thought was unusual. They never got any hotter but I believe both engines have 140 to 160 thermostats. There was ample amounts of water coming out of the exhausts so any help would b most welcomed...

    Bidge Pump

    One of my two bilge pumps will not shut off even when there is no water in the bilge. My rocker switch also indicator light is also on even when the rocker switch is in the off position. The only way I was able to turn off the pump was to disconnect two wires on a common wire terminal connector...

    Alternator Output

    I decided to check my output voltages on both alternators by placing my ground wire on the negative post on my battery and the positive lead off of the orange wire post on my alternators. Both alternators output voltage was lower than each batteries reference voltage. Could I have two bad...

    Trailer Upgrade

    Over the past 6 months I have been trying to make a decision to either upgrade my float on aluminum trailer or purchase a new one. The trailer that came with my used boat was thrown in to sweeten the deal. The problem with the trailer is that it was too small in weight capacity for my boat. So...
