    Inaccurate fuel gauge?

    Nola Mike; You say: ' to account for the attitude of the tank'. It may be just that, the angle of the tank creating a bad reading at the level sensor. On my boat, when stopped, the fuel tank is not level, in leans down at the front, and my gauge is at the back, so I read always lower than...

    Stern drive rising up on its own

    Check the breaker behind the engine near the distributor. It has a red button.

    Trailer Guide Ons DIY?

    On my trailer, I tried first the vertical posts uprights. In theory, they are perfect to center the boat. The reality I found, is that since the boat is wider in the center and the posts are at the back, they can't be adjusted to touch the boat because the boat won't pass between them (middle...

    Engine overheating

    Problem found! On the raw water pump (Volvo, on the crank pulley), there is a oil seal that keeps the water from flooding the bearing, and keep air out so the impeller can create suction. From what I read, when that oil seal fails, water goes out in the bearing. Only a few times water get...

    Outdrive trim pump, where is the power source

    Update on my trim motor repair; I took the boat out for the first time since my repair. The motor was working fine in my driveway. On the water, it was working fine at first, then, after forcing at the end of the down travel, it stopped working... for a while, then worked again. The only thing...

    Engine overheating

    Chaparral 260 Volvo Penta 5.7Gi-D / Duoprop SP-SM I can't find the problem. The boat has been working fine last year. I winterized it like usual, and removed the outdrive for inspection and to change an oil seal. I reassembled everything this spring, and went last week end for the first ride...

    Electric windlass wiring problem

    Chaparral Signature 260 2004 Hi all. On my boat with electric windlass, I have a 50A windlass breaker behind the battery switch door, PLUS a 50A glass fuse under the helm near the buss bars. The 12V from the fuse goes to the anchor switch UP-DOWN. Everything was working fine before I touched...

    SX outdrive stuck or was now broke :(

    What keeps your gear from being pulled is the inner race of the bearing #10. It is press fit, but not that hard. On a bench, only a hammer and tube is enough to make the gear move. So, try to find a way to pull on the gear, or pry, and it should go out.

    tilt trim system

    I had a similar problem as you have. look at this, and to post #9 for your answer. https://forums.iboats.com/threads/outdrive-trim-pump-where-is-the-power-source.740671/ On mine, the problem was caused by a seized trim motor, which was full of water and rust. After cleaning and lube, it worked...

    Refrigerator 1.9cu ac/dc

    You didn't say if the problem was on AC or DC or both. On my boat, the fridge was working fine on AC power, but on DC, it started, then after 20s it stopped. The problem was 2 things. 1. the breaker was resistive and dropping voltage 2. the ground wire was resistive also and dropping voltage...

    Shimming Bearing Cover DP-SM / SX-M

    I was in the same 'boat' as you... I had stripped threads but didn't want the expanse and trouble of shimming a new cover. I cleaned and degreased the cover, applied JB Weld around the circumference, and tap with new treads. It seems solid. I did that a month ago, so didn't try it yet, but I'm...

    Charging voltage drop with diode isolator

    Thanks for the info. Yes the 'excite' is internal and I won't modify the alternator. The Argo isolator 'FET' semiconductor seems to be a good solution, with a maximum of 0.1V drop at high current, and less drop at low charging rate. Either that or the ACR, but both seem to solve my problem...

    Charging voltage drop with diode isolator

    It makes sense. I just found on internet the manual on my diode isolator, and they say to cut the B+ wire and pass another wire to the isolator. I'm surprised that my boat didn't come already equipped like that from Chaparral...

    Charging voltage drop with diode isolator

    Yes the orange is tapped off at your blue arrow, and the other end seems to go to the relay box. The Red you are pointing to has one end to the ALT output (new wire), but the other end is buried in the wire loom.

    Charging voltage drop with diode isolator

    Jim, those smart chargers, are they only on 120V? Or they can be installed between the alternator and the batteries, in place of the isolator? It seems that a ACR is installed on newer boats. If I replace my diode isolator with a ACR, I will gain 0.7 volts when I'm driving the boat, would...

    Charging voltage drop with diode isolator

    alldodge, my alternator output seems to go to the relay box. Take a look at my other post, I have some pictures. https://forums.iboats.com/threads/alternator-b-wire-vs-relay-box-volvo-penta.742318/ but it's possible that after a relay it goes to the isolator. Here is a drawing I made of what 'I...

    Charging voltage drop with diode isolator

    I find that my batteries could give more when I am 2 days at anchor. At home, with the 120V charger, I have almost 14V at the batteries. So they are fully charged when I quit home. On the water, when the engine is running, there is like 13V at the batteries and 13.7 at the alternator B+ post...

    Alternator B+ wire vs relay box Volvo Penta

    I was inspecting my alternator wiring to see if there was a 'S' terminal to see if I could increase my charging voltage, anyway, this is what I found. The big orange wire going out of the alternator has been cut and another wire (red) connected to it. I found that originally, the orange wire...
