I have a 97 150efi on a ranger boat. It runs excellent 5600rpm and over 60mph. Idles excellent. I keep it well maintained. I use seafoam in the fuel all the time because i question the gas you buy today and alot of stations in the northeast now have 10% alcohol.
My problem is that it starts alittle hard when cold. I prime the bulb and advance the idle....but unless i advance the idle way up, it wont start. When it does i have to be quick to pull it back off high idle.
Once started, it will start then on by almost looking at the key.
Maybe a sync and link.....tps senser???? or is it just the way they start?

Don't know about the fuel injected models, but my carbed 150 likes the fuel dumped into it on the first start of the day.
