Re: Sea Ray Signature Series boats
Wow, you are looking at nearly the exact same boat I just bought. 1999 Sea Ray 190 BR, 5.0L Mercruiser Alpha 1. I live on the Oregon coast, so since I have had it, I have only been able to take it out twice, (only for a few hours each time) due to the rain, so I can't give you any real first hand information. We even got snow one day, unusual on the coast, ESPECIALLY in mid April. I can only tell you what the dealer told me. He said that yes, the 5.0 will get a bit less GPH than the 4.3, but since you don't have to push the motor as hard to get a certain level of performance, you will only end up using slightly more (maybe a gallon) fuel over the course of a full day of boating. Sorry, but I can't give you real numbers. Also, mine came with the carbed version of the motor, and he told me that while it isn't quite as efficient as the fuel injected, here in Oregon they are putting Ethanol in the fuel, and it either is causing, or has the real potential, to cause some real problems with fuel injectors. He told me that many people are only buying boats with carbed engines now. I don't know where you are, but you may want to find out about the fuel where you live, and if it is a concern. Good Luck.
