Merc 135 suppressed plugcaps

[AndyL]

I have recently fitted a new VHF and am picking up a lot of engine noise over weak transmissions. I have re-routed the cables, replaced the aerial, run a seperate aerial and wandered around the boat with it, but it would seem I am getting RF from the engine. I have been advised to remove the standard plug caps and replace with suppressor caps. Is this likely to cause any problem with the ignition system.<br />Motor is 1993 V6. Thanks<br /><br />Andy

It should not cause any problems.<br /><br />Also try to put a noise filter on the hot lead of the VHF radio.<br /><br />Available at any Radio Shack.<br /><br />That will further reduce interference.<br /><br />Kenny

Thanks Kenny, Will go ahead and get the caps. I have fitted magnetic inductors to all the leads but it really did not make any difference. I think my new VHF is much more sensitive than the old one as this was never a problem before. Will drop a line with teh results. The weather has turned bad here so don't think I will get out for a few days.<br /><br />Andy
