    1958 Evinrude 7-1/2 Fleetwin carburetor overhaul

    I read the procedure on adjusting the high and low speed jets and it says to adjust the high speed jet first, then the low speed. Is that due to some interaction between the high and low speed mixture adjustments that requires the high speed to be adjusted before the low speed? Is there a...

    1958 Evinrude 7-1/2 Fleetwin carburetor overhaul

    That's what I did. I trimmed the ends of the hoses first and they were much tighter going over the fitting. I need to buy a couple more ties so I can get the tank end fixed. I was surprised the o-rings in the hose fitting weren't like stone - they were actually soft and pliable but since I...

    1958 Evinrude 7-1/2 Fleetwin carburetor overhaul

    I was able to get back on this project the other day. Pulled the lower unit to replace the water pump impeller and discovered why it wasn't pumping water - one of the fins was broken off the impeller. The worst part of the whole job was to clean the 62 year old gasket from the powerhead. It...

    1958 Evinrude 7-1/2 Fleetwin carburetor overhaul

    I'm in the process of overhauling the carburetor on a 1958 Evinrude 7-1/2. I purchased carburetor kit #439071 from my local dealer. There are some parts in the kit that were not in the carburetor I disassembled - there are some translucent plastic washers which I believe go between the packing...

    Mercruiser 5.7 EFI slipping/over revving

    I was out on Lake Michigan this afternoon and the waves were about 1' and my boat was running fine. The waves built to 2-3', then 3-4' so I headed back. My engine over revved and it acted like it was slipping. At 3200 RPM I was only running about 10 MPH. It typically cruises at 24MPH at that...

    '97 Sea Ray Sundancer fuel pickup fitting removal

    '97 240 Sundancer, 5.7 EFI. When the fuel level drops to 7/8- 3/4, the engine runs rough at idle and below 1200 RPM. When accelerating from idle, the engine runs rough and backfires. Once it planes off, it runs fine. I filled the fuel tank, everything was fine until the fuel level dropped below...

    AC Delco MR43T Spark Plug question

    I thought I'd replace the spark plugs in my 1997 5.7 EFI since they have 556 hours on them. The Mercruiser parts manual stated AC Delco MR43T so I bought eight at the parts store. I started to replace them and when I pulled the first one out, the existing plug was a half-inch shorter than the...

    Replacing corrugated plastic crankcase vent hose 5.7 EFI

    I am going to replace the corrugated plastic crankcase vent hoses from the valve covers to the flame arrester since they do not seal properly on the fittings and the oil eventually accumulates on the valve covers. I know that it must be oil resistant but is there any other specs the hose should...

    EZ Loader Sure Lube bearing system

    I have a EZ Loader trailer with the sure lube system. I replaced all the bearings two years ago and I have another bearing that is slightly rough. I replaced one of the axles when I bought the boat since the tortion axle was bent. The new axle does not have a vent hole for the grease like the...

    I am in the process of replacing the trim limit and trim indicator senders on my Dad's 1976 Slickcraft SS-235 and noticed corrosion in the bell housing area where the shift cable comes through. Upon further inspection, I noticed the sheath on the shift cable was split and corroded so we're...

    Replacing Trim indication and position sensors on Alpha 1 Gen 2 drive

    My trim gage began acting flakey and then went to the full UP position. I figured it was the trim indicator sender on the drive and sure enough, one of the wires was rotted off. I took the sensor apart and attached a new wire to it to get the gage on the dash working but would like to replace...
