    SP drive, short/long hub, spacers, cone, lock bolt...

    I'll try to keep it short and simple I have a 1990 model SP 230 drive with a 2.3 aq131 I was given a new prop that is the "long hub" type, where as my current prop is a "short hub. After installation, the nose cone only grabs a few threads and the locking bolt in the end doesn't reach the...

    AQ131D /230sp drive Propeller & temperature questions

    Just got this boat in the water have owned it since last year. It seems like it won't stay on plane unless it's pushing over 4,000 RPMs. I want to try a different prop but I have no idea what's on it as there are no identifying numbers. What propeller fits the 230 drive from 1991? It seems like...

    exhast manifold rust, winterizing

    About a month ago I took it out of the bay and removed the four drain plugs on the 4.3L (mine is a 1990 model year), Today I went and stuck a pick inside the drain holes and broke though rust causing all the water to come out from each manifold so they were plugged as they often are. . The...

    Just getting the 90' doral ready, and an issue I seen earlier in the year still exists...when started and left idle, temperature rises to about 200 and will quickly backs off if I give it some throttle, sometimes backs off on its own without giving it throttle. My first thought was impeller not...

    well coming in late evening with the sun glaring i missed the final buoy and took a turn into bad waters:facepalm:...doing no more than 10 mph I found myself in ~2 ft of water with smooth rock, hit the outdrive followed by an awful rattling/vibrating. I quickly threw it back no neutral but the...

    Ballast Resistor Mounting...a quick tip

    Well we put in a resistor with the new coil, bypassing the resistor wire. It only came with a pre-cut length of wire and the resistor was kind of hanging there (with unprotected leads that could short out)....My buddy grabbed a zip tie and put it on the cold water intake line..I was worried it...

    Running omc 400 on garden hose

    Can a late model stringer (1985) run on earmuffs? I know the older stringers had a water inlet above the prop so muffs would not work, but mine appears to have inlets on the sides like my mercruiser. There is no hose attachment like some of the older 70's stringers. When I bought the boat the...

    No ground @ coil...safety switch?

    So the boat will not fire up today. Quickly figured out there was no spark. Grabbed a multimeter and tested the + and - on the coil, it is 0 while sitting and 12V while cranking, but ONLY if i touch the negative lead of my meter to the metal engine block, it appears that the (-) side does not...

    stringer 400 trim

    The trim works to the best of my knowledge, at least..When i press the trim buttons i can hear it working. I'm not familiar with this style of "engine tilt" set up, but it really doesn't seem to do anything on the water. Ive played with it many times and it doesn't seem to change anything. Not...

    2.5L omc overheating

    I posted a while back about losing power in my 86' 2.5 with the older stringer drive. I noticed it took quite a while to warm up, and when it did i got more power and less bog. Today i set off and within 5 mins temp was in the red, but when i throttle back the engine would cool off. My guess is...
