I just got my boat done. My original starter was no good so I bought another one from a chevelle. It cranks but spins off and grinds. Tried shimming it but it would grind even worse. Turn out they gave me a starter for 350 instead of 454. Just got back and tried putting the new starter on but now it's too bulky and big it hits the tunnul part on hull. No clearense. it's a marine 454 motor. Any ideas on what starter I should try getting. I heard about top mount starter but kinda short on cash. Any ideas?
Can't you put the old one and any new one side by side on the counter and tell if they're the same??? As I recall, the "field" body is the same diameter for GM starters for about 50 years or more, and a 350 and a 454 MK IV block should take the same one. (Assuming this is for a MK IV block w/ 168 tooth flywheel/flexplate.) Do you still have the old one?? If you do, use the old nose and maybe the kicking out/grinding might go away.... One more question, are you using the knurled starter bolts?? Are you using a "brush end" brace to the block?? A "high torque" GM starter is about an inch longer than a standard torque, but the diameter is the same. The high torque requires a spacer to attach to the solenoid..
PS I've been doing this stuff for over 50 years and I've never shimmed a Chevy starter, never.....
PSS If your 454 is not a gen 4 disregard this post...
Nvm I got it going good. I was searching last night and like u said, the knurled bolts. I had one bolt I went to go buy from hardware store, same size and thread. Just not knurled. So today I went and got another 454 starter and new knurled bolts and bammmm!!!.. fires right up no problem. I must need to figure out why it shuts off once I tap the throttle. Maybe timing needs more adjusting
Sorry for the inconvenience, and maybe a dumb question. But I just got back from the lake. Took the boat out for the first time to check things out and seems like I'm not getting water fed.. at first my headers would throw out steam but when I noticed my temp rising up to 200°, I noticed that steam or mist wasn't coming out headers. Even on the weep hole, only hot steam was dumping out. Boat runs fine till it heats up. Headers are dry at idle and it'll cool down to about 180 but once I take off driving, no water or steam come out headers. But steam does come out dump weep hole on back of transom. I just took off basset T and ran water hose water thru it and it opens up just fine. So I'm thinking jet isn't supplying water to block like it should. Any idea? My plumbing consist of, jet to gate valve, from this gate valve to T and from that T to the block.. and from thermostat housing, got one line going to gate valve and out dump to transom, and other line goes to basset T and into headers. Sorry for long post and for inconvenience. Hope it something real simple. Thanks
Ok. I'll try that. Last week I ran water hose thru gate valve to motor and steam was coming out headers and water coming back out to dump fine. Hopefully it's something simple. But yeah ill try that once I get off work tomorrow. If any more ideas please post thanks
