I have a 1991 Evinrude 60' V6 175hp E175GLEIS.
Port side cylinder head, center plug threads are very damaged.
I am considering tapping the threads and using a Helicoil etc.
Yet, I was able to find a local guy (MA area) with some parts that may/may not work for my motor.
The stamp/marking on MY cylinder heads reads 337548.
The stamp/marking on the REPLACEMENT cylinder heads I was able to find reads 338311.
Questions:
1. Are the 338311 cylinder heads compatible with my motor?
2. Differences between the 335748 and 338311?
3. Any harm to the motor having 1 of each installed or do both cylinder heads need to match?
4. Any advantage to using the 338311?
5. What is does the "hot head" term I've read online refer to?
Thank you very much in advance for any information possible.
