    Volvo Penta AQ131D to AQ260B rev 8

    http://forums.iboats.com/showthread.php?t=315841 is the post that suggests complete success. One more tiny lingering detail remains, fouled plugs. I've got 9.5 v at the "+" at the coil with key on, I've read on BID ignitions it's supposed to be 12 V all the time not just during cranking. Can I...

    Volvo Penta AQ260B swap from AQ131D rev4

    Last one guys, in swapping motors I've stumbled on the fact that I have BID ignition instead if a points condenser setup, presumably from as AQ271 or AQ311 that's OK without the ballast resistor, but I do have the wiring harness on the motor for an AQ260A/B the one (WITHOUT) the relay but my old...

    '89 AQ131D Volvo Dist. Springs

    So finally removed dist. as even with different spark advance degree tries wasn't really getting anywhere. Found condenser/capacitor to probably be the main issue. Have a picture showing the offending part and the dist. springs. Are they supposed to be two different sizes? The weight with the...

The SP/A MT leg I have is...

    Hey guys back from 2 weeks holidays and burnt a 20A fuse for my tilt device. It's an SP-A/MT leg and tilts up fine and am convinced that the down relay switch is out as it doesn't do anything not even click on the down. Trouble I see is the orange light on the dash that indicates leg is full...
