I'm new to boating and have just purchased an '88 16.5 foot Sportcraft bowrider, with an '88 (I think) Mariner 100 engine. Hoping to get some info on the following:1 - I've read some of the posts, however I'm not sure if I've found the answer to correctly starting the engine after it has sat for some time. What I do is advance the fast idle about 1/2 way, turn and push in the ignition (it says push to choke). I hear a clicking sound much like a failing car battery on a cold morning, however the motor does not turnover. A second attempt results in more clicking and a slow turnover of the engine. A third attempt results in a fast turnover and engine start. Can someone advise the correct proceedure? Is there something that needs looking at? The serial # of the motor is 0B301044.2- After startup the engine seems to run fine. At full throttle it smoothly revs around 5400 and pushes the boat to 43-44 mph. However at around 1600-1700 rpms the engine runs rough but smooths put again at lower rpms. Is this normal and acceptable operation? 3- The boat was stored over the winter with minor winter maintenance done, is there normal maintenance that should be done? How can I get info on the proper operation and maintenance of the motor? The only thing I notice is a slight stiffness or jerking of the steering which improved after greasing.4- Any idea on where I can get info on Sportcraft boats? On the web all I can hind are offshore larger models. Is the brand no longer made? I would like info on care and maintenance as well.Thanks in advance for your replies.

Your engine is a 2+2.It runs on 2 cyls below 1700ish RMP'sWhen it hits 1700ish..the other cyls cut in.If it is boggin at that area...when you crack the throttle it will need the Accelerator pump looked at.But if you push the throttle slow..yes you will have a rough engine at 1700...especially if you wish to cruise at that rpm.TMD
