Those are gel coat stress cracks due to flexing of the transom. You could refinish it but will come back. Best way to handle it is to keep it waxed/water proofed. Permanent solution is to beef up the transom but not necessary at current stage nor would it be a worthwhile investment. Enjoy your boat. It looks like a great buy and with many years of service left.

What do you recommend for waterproofing? 5200?

My vote is no big deal -- but keep an eye on them. Gel coat is very brittle and would rather crack than flex. All materials, under a load, particularly a shock load, will flex, and if properly designed, no harm will come from that flexing. For example, wood (which your transom may be made of) is exactly like that. Tree branches couldn't survive otherwise.
Excellent point. Fiberglass boats flex and move a lot more than most people think.

I would drill a small hole at the end of each crack, then patch and fill. The drill hole will keep the crack from spreading.

I’m not sure if Sea Chaser leaves the transom finish like that when new, if not, the texture means it’s been reworked at some time.

Cracks may mean nothing, or they could be the sign of problems that need attention.

Tapping on the surface with a hammer is an unreliable method of testing.

Your best bet is to route out a few cracks to see if they go all the to the core, if they do, the core is most likely wet. If the core isn’t affected, then refill the area with epoxy. This is very easy to do.

If the cracks go to the core and it’s wet, then you need to plan what the next step needs to be. Wet doesn’t mean it will fail soon, only that before to long it will need some attention.

If the core is beginning to rot (assuming it’s wood), then the plan needs to be a little more urgent.

Checking to see if there’s a problem is easy, trying to convince yourself there’s no problem without checking can be a nagging worry.

Just purchased this Sea Chaser 186 for fishing the bays. Great ride and condition for $9k.
Unfortunately I did not spot these before cracks before I purchased. The previous owner never used a transom saver, which I know is a hotly debated topic. Is there something I should do to repair? Get a transom saver?

These cracks are on both sides of the outboard. Dollar included for scale and metaphorical purposes ;)

Can you get feedback from the manufacturer?

Based on what I've read from Sea Chaser the done use wood in the transoms. BUT I'm not sure what they do use haha. I'll be speaking with them this Monday.

Try to get a moisture meter and check for water intrusion. You may find a surveyor that will take a look without a complete survey.
Once you determine if the transom is good, follow the instructions posted to open the crack and gelcote them closed. A good gelcote guy can work the area so it is invisible.

Having completely rebuilt 3 different glass boats, Undone's given you some really good advice. I'd do what he's suggested and then use a transom saver correctly going forward. With boats, as most things, the devil really is in the details.

Thank you all so much for the help. I will keep you all posted with my findings. I'm going to Dremel out the cracks for further inspection. If all is well I will then fill with Marine RX.

Have seen a few other Sea Chasers online with a similar "failure". I believe it is cause by trailering without the saver.

@undone youre very observant! After looking closer it does appear to have been repaired or refinished at one point. It only seems to be the top of the transom and no where else. Before I do anything I will be trailering it out to Lakeside to KMG repairs to have pro take a look. The boat runs unbelievable and takes on no water BUT I will be grounded until this is all resolved.

Great news guys! Had Kevin at KMG boats in Lakeside take a look at the cracks at his shop... He confirmed they are in the gelcoat and that transom has clearly been worked on/repaired too. He also said the transom feels solid and that I should just keep a close eye on the cracks... Specifically if they change directions and/or start to get wider. He is a big fan of transom savers, and did mention that the cracks are gonna keep happening but are very normal.

Check out his boats on YouTube or his website, unbelievable workmanship. KMG Boats, Lakeside CA.
