    Bimini Top

    Re: Bimini Top This bimini stands up fine to 40 MPH. In fact, because it tends to act like a wing and lift the hull, with it up, my speed jumps to 43. Just remember to twist the hold-down straps 4-5 times and they will not flutter in the wind.

    Chrysler 140 running out of gas

    Re: Chrysler 140 running out of gas Your fuel pump pressure is right on. No problem there. Definitely replace the 1/4 inch line--it is insufficient for the fuel needs of that engine. Go 3/8 with everything if possible. Then check the routing of the fuel pump hoses: The lower pump...

    need to raise transom 2 to 3 inches for 20hp

    Re: need to raise transom 2 to 3 inches for 20hp Here is one I did with a 5 inch lift. >080 aluminum is sufficient for a 20 HP engine and you won't need the side braces like I have. Although I show a piece of wood inside the aluminum, I actually filled it with fiberglass--get this--resin...

    how to test trigger

    Re: how to test trigger Sounds like a bad CD box if there is no voltage on the grey wire. See: When the distributor signals the transistor inside the CD box via the electric eye, that transistor dumps the capacitors into the coil for a very fast voltage rise and a very high, sharp spike of...

    Two wire trim to three wire trim

    Re: Two wire trim to three wire trim here is a harness I made from oval relays rather than the square ones but shape does not matter. As long as they are 5 pin they will work. The red wires are power to the relays from the battery. The black wires are grounds. The purple wires are power...

    Springs!

    What brilliant engineer at E Z loader had the idea to use aluminum spring hangers? Now I don't trust using this trailer until I replace them with real steel hangers. I wish I had seen this BEFORE I put the boat on the trailer.

    How much "Transom Flex" is too much...

    Re: How much "Transom Flex" is too much... In this instance DONT listen to NSBCcraig: With your Chrysler/Force, the engine clamps tend to bite into and deform the transom fiberglass. Eventually this causes the trim cylinder ram to move off the stainless seat on the steering yoke and trim...

    Wow! I may be in trouble with flex, and now I see why.

    Re: Wow! I may be in trouble with flex, and now I see why. That is too beautiful a boat to let a little thing like a rotten transom cause you to sell it.! We more experienced fellows here on the forum do tend to take repairs for granted and consider simple what a novice would consider...

    2 Bladed prop on 100hp Merc. Is that the right prop???

    Re: 2 Bladed prop on 100hp Merc. Is that the right prop??? Back in the day a two blade BRONZE prop was the only way to go for speed applications. The third photo shows a bronze two blade, solid hub, Mercury racing prop. Brass is an alloy of copper and zinc, Bronze is an alloy of copper...

    How much "Transom Flex" is too much...

    Re: How much "Transom Flex" is too much... On an 18 footer, there should be NO flex of the transom. Just to be certain, while the boat is on the trailer and with the engine vertical, stand on the anti-ventilation plate and bounce. You should see NO transom movement. Now if your transom...

    thinking of a bimini

    Re: thinking of a bimini Oh! That's going to be a great Sunday ride. Yeah, a small Bimini will provide you with shade and can be used at cruising speed. Yes, they fold down out of the way. You may need to buy slide rails to mount it on so you can slide it back or forward to get it out...

    1988 Force 125, will a thru hub prop work on a non thru hub engine

    Re: 1988 Force 125, will a thru hub prop work on a non thru hub engine YES!. AND---There is no difference in performance. However, you must be certain you are buying a small 4 inch diameter (hub) prop, like for a small gearcase Mercury 90. Bigger Mercury engine props have a larger hub...

    What is the theoretical speed of my boat?

    Re: What is the theoretical speed of my boat? At an engine speed of 5000RPM with a 15 inch pitch prop, your 1.73 ratio lower unit, and a theoretical 10% prop slip, your theoretical top speed would be about 40 MPH. At 5500 RPM it should be about 44-45 MPH. To figure it yourself, take engine...

    effect of trim on speed

    Re: effect of trim on speed James: having the engine tucked too far in will drastically affect speed and performance. The engine will constantly be pushing the bow down, increasing wetted surface and slowing the boat. As a POOR example, On this boat, I tuck the engine all the way in for...

    gas mileage question

    Re: gas mileage question This 14 foot little thing burns 15 gallons per hour at full throttle at 60 MPH. I use it to zip up and down the river for an hour or so and then go home. I really don't care how many gallons per hour it uses and I don't care how many miles per gallon it gets...

    Chrysler/Force cooling water

    The question is frequently asked: "How much water should issue from the back two holes in my engine?" The definitive answer is: It depends! Water comes up the water tube and passes through the block. If there is no bypass, ALL water exits from the rectangular hole in the back of the match...

    1975-1976 Chrysler 75 hp prop question.

    Re: 1975-1976 Chrysler 75 hp prop question. Those 18 spline thrust pin props are becoming more difficult to find but there are a couple on ebay. As far as re-hubbing them, I don't believe that anyone makes new hubs for them so your only option on your current props is "pinning" them. You CAN...

    Coil Mod part 1

    Re: Coil Mod part 1 TOM: You can buy a hub from HMS hubs for around 20 bucks plus shipping. I don't have the catalog in front of me but you would buy the 80 durometer for stainless. If you have access to a press, you simply press out the old hub and using an old tapered bearing press in the...
