Newbie question on mecruiser inboard

[outdoor4500]

Hi all,<br />I am new to this board and new to boats and motors. I know nothing about them but bought one recently. I have an inboard mercruiser v-4.<br />My question is...I was going to use this boat for the first time so I hooked up the muffs to the intake with a water hose to start the engine to make sure it all worked.<br />When I started the engine water came out right at the bottom of the motor right against the boat....don't know what it is called but it is a small little hole located on each side. Can anyone tell me is this normal..where is the water supposed to come out?<br />I know this is a dumb questions but I need to learn this stuff.<br />Thanks for your help.

Re: Newbie question on mecruiser inboard

On your i/o system this is normal. These holes are backpressure relief holes. Water should exit from these holes and through the prop hub.<br /><br />BTW welcome to iboats. There are a lot of people here that are more than willing to answer any guestions you may have 24-7.

Re: Newbie question on mecruiser inboard

There is a difference between a straight "Inboard" and an I/O. The I/O has the oudrive on the back of the boat and this is what I am assuming you have.<br />Those 2 holes are about an inch in diameter and are exhaust idle reliefs, and yes it's normal for water to come out of those when on the muffs.<br />What year is your boat, and what engine do you have? Never heard of a V4, You may have an inline 4 or even a V6 or V8.<br />Anyway, here is a link for a 2001 Mercruiser I/O owners manual that should help you with some terminology and how to information.<br /><br /> Owners Manual
