    New props

    Looking to put new props on my engines. 250hp ox66 on a 280 marlin. Not looking for anything special. Almost exclusively run 1 hour at 3800 rpm/30 mph to fishing grounds then troll for awhile and come home at 3800/30. At a loss as to what to pick, to many options

    low rpm in gear

    there did seem to be some variation in max rpm, and it did vary how long it took to get to max rpm, but did seem to stick at max rpm when it got there. did not seem like a computer limitation to rpm to me

    low rpm in gear

    A neighbor just bought a used boat with twin 2004 Yamaha 200hp 2 strokes. I went with him for the sea trial all seemed good. A few days later he asked me to go along for the ride back to his dock after purchase and the port engine would not go over 3000-3100 rpm under load. It seemed to...

    on my 280 marlin with 1998 250 ox66, the best i can trim out at is 30mph burning 21.5-22 gal/hr. that is ideal conditions. for completeness add in 1/2 gallon oil per hour as well

    Electrical gremlins/switch panel replacement Sailfish 272

    the most useful tools to chase gremlins will be a multimeter, jumpers (alligator clips with good length of wire between) and a good size needle, i use a 20 ga hypodermic needle but a stout sewing needle works just as well to stab insulation on wire to establish contact for voltage, ground or...

    anchor/anger management

    We have started using the Grady for other than fishing. This is usually anchoring off a sandbar or island and enjoying lunch and a swim. The learning curve for setting anchor seems to be as steep as docking but I am slowly getting the hang of setting both anchors, unless it is windy or strong...

    Replacing failed Guest Charge Pro 2722-B on-board battery charger

    don't your 250's have aux charge leads? if functional (mine are not) they should handle charging house bank when running and not need an acr. you will need a third battery switch if you go with 3 banks. i would go with 3 banks, 3 1-2-both switches, and a 3 bank charger using original 30 amp...
