    No water coming out the Merc tell tale now?

    when you buy a used motor, you need to do all the maintenance the prior owner didnt do before they sold it. impeller, gear case service, PTT fluid service, new plugs, etc. you did check the motor over prior to purchasing and at least did a compression test?

    Boat Tarp Material?

    I have a boat cover and I use a 10x20 canopy over the top. a boat cover by itself breaths and doesnt get mildew. a boat cover covered with a tarp will get mildew

    2003 Chris Craft Launch 25 - VolvoPenta engine replacement - need engine advice

    there is no horsepower limit in I/O motors. so you could put 500hp motor in there. however a new 5.7 longblock dropped in with new manifolds, etc. should be in the $8-10k range your looking at over $20k for the new 5.3 or 6.2 LT based motors. If it was my boat, I would strip out the fuel...

    leaking riveted starcraft ('82 MR180)

    something to think about the last 3 plastic thru-hulls I had to replace was because the flange broke off. plug would not help that situation back to the leak. double check all the thru-hulls then look at the rivets/seams

    Prop for Homemade Pontoon

    here is an anology. a houseboat with twin 454 big blocks moves at 8mph. the same houseboat with a 50hp motor moves at 8mph. that is the displacement speed of the hull even with the 150hp motor, I do not see that pontoon getting to 25-30 on the water. at a minimum, you would need lifting...

    leaking riveted starcraft ('82 MR180)

    Remember, livewell pumps are rated at 0" of head. So if the rise from the pump to the discharge is 1 foot and you have 6 feet of hose (~1' of additional head) you have to look at the chart for the 2' of head. Which is closer to 600gph

    Salvage auction boat - can this be repaired?

    Can it be repaired. Yes If you do the work yourself, expect $7-10k. You will need to hand-make a mold section If you pay someone. The cost will be huge. Assume $100-$120 per hour labor on top the materials

    Bought my first boat to cut, gut and rebuild from bow to stern, including engine. Killed my back and suffered the wrath of the fiberglass demons

    Grew up with Mercs. Some older johnnyrudes, some Atwaters, Mac's, Hiawathas. The Mercs always had more power for a given rating.. rating was at 3/4 throttle and above that was "reserve". At least that was the story I got at the time Dad had a buddy (Merc and Tecumseh contact) do some work...
