Re: mercury 135 oil tank
You should first consider troubleshooting the reason for the buzzer and fix it. It may be a simple and low cost fix. While others may disagree, a motor with a working oil injection system is worth more and is less likely to fail due to operator error (e.g., user forgetting to put oil in the gas tank or not mixing the oil well enough to avoid raw gas going into the fuel line). Just my opinion...
