HONDA Bf 7.5 service info.

[CORBIEREV]

Need to service my Bf 75 (1978-87 model), early one with contact breakers.
I know Clymer do a workshop manual but don't know if it covers the engines with points.
Anyone with info of settings, websites, scans of manuals etc would be a great help to a budget sailor.

Regards, David.

I used to have one of those. Honda UK don't sell the workshop manual any more, but sent me a photocopy of their manual for not too much money.

I have the Seloc manual and it covers the BF75 with points.
You can get it from Amazon. Seloc honda manual It's about £18

Send me a PM with your e-mail, and I will send you the Volvo Penta Saildrive MB2A-50S Workshop manual. Its a BF 7.5 without the top cover, and a rubber doughnut. It has all the settings. I have the later electronic setup for it which bolts straight on.
I also have a spare few bits and pieces like alternator, pull ring and prop/spinner, lower leg gearbox if you want them. All cheap.

Sold the boat so no longer need them. Was getting round to E-Baying the lot.

Cheers

Jim

I have a B75 K3 still in regular service. This is a very similar engine. The manual states twelve to sixteen thousanths of an inch. In practice I use a buzzer and battery to set the points on the firing mark as this is far more accurate.

In the Seloc manual it also uses the point of opening (using a bulb) for determining the timing. However that doesn't set the dwell, which is (as I understand it) as important, so a gap setting would be needed as well.
(Unless of course there is no timing advance possible, other than by adjusting the gap)

 

[the_wanderer]

The bulb system is just the same as using the buzzer, it detects the exact point that the points open thereby producing the spark. I have found that this is the most accurate method of setting this particular engine. I have a dwell angle meter which is now redundant for the cars I used to run. This will not work on this engine.

Regards.

Alan.

Hi, I am in desperate need for a part for my lower unit for my mid 80's Honda 7.5 HP. I need to replace the round collar that goes over the propeller shaft and bolts to the lower unit with 2 bolts. Any possible help? Thanks, Dennis Noordam
