Replacing the magnetron is relativity easy project
so would agree with the suggestion to replace that part. Have replaced over 20 of them in microwaves and my airplane's radar. Not a difficult job as long as the power is off and you ground or short everything before you touch it. (important unless you are trying for a new frizzy hair style!
) My airplane's magnetron is supposed to be replaced every 3000 hours of usage. So seems logical your boat's unit will also get weaker with time and usage.
Plenty of info avail on how to do it might be good idea to read it over. Google
search on replacing radar magnetron lists 7,430 articles which is way more than you need! LOL!
Though not in the money saving venue feel must mention that since 90% of an iceberg is under water
and you are going above the Artic Circle I would seriously consider a Forward Looking Sonar. Have one on my boat and just in a trip from the Med to Southern Florida
6 weeks ago (March) our sonar found and clearly warned the boat of 7 potential diasters.
4 underwater rocks, 2 containers 5 & 6 feet below the surface. In the case of the one @ 5' the underwater camera
got the name and number and when the Captain
called them they could care less. Told us it was now the property of their insurance
company and they had no comment on how it was going to be taken care of. Captain
logged the call and forwarded copy to our attorneys. Texas
is one party state and call was from middle of ocean. The seventh contact was a whale! Did not know that it could detect them and would not have wanted to hit a whale even with a steel hull
Icebergs would worry me with the greatest part of their mass underwater. Do believe a forward looking sonar esp one that reaches out 180 degrees would be a great safety
addition for you. They are not exactly cheap
IMHO but what is the safety
of my family
or me worth to me?
Realize not telling you something you didn't already know just prefer to error on the side of safety.
Have a Safe and Wonderful Trip!
